Step by step, full explanation of how to avoid future problems, like drilling the cross member. This gas tank install is so much better then the factory behind the seat tank.
Thanks Dave!
My pleasure!
Thank you so much for sharing your knowledge...👍👍👍
Man oh man! Every video you do is absolutely clear and complete. Even when it comes down to why you do it a certain way, you give us the reason why you do it that way. When your all done it is a complete install with all the questions answered. I'm going to look for the video for the filler neck.
Thanks for doing these instructional video's. It sure make me feel more confident I can do it myself. I only need to decide if I'm going to keep the carburetor or go with EFI, but either way, the tank is going in the back.
Love the videos. Long time consumer. Very inspiring to get my truck up and running.
Thanks man! Get on that project!
Followed video step by step and install went perfectly. Only thing I would recommend differently is after cutting seal plate in rear of bed to clear new tank - I cut two pieces of 1/2 EMT conduit (fits perfectly side by side) to bridge the gap on the inside of the channel and welded it for additional support and reinforcement
Excellent feedback and suggestion! Thanks for watching!
Robert do you have a photo of this, I am curious how it is set up
Nailed another video. These are so helpful and I am using them on my 74 jimmy
thanks so much for the help
will definetely order from Brothers
Thanks for watching!
Hi David, just wanted to say how much I enjoy these videos. I’ve watched everything from rust repair, to brake upgrades, to this fuel tank video. You are a natural teacher, and have a great ability to provide encouragement and confidence to beginners. Hopefully this pays dividends to Brothers Trucks too, so they keep you busy making more videos.
The air hose should be ran high up inside the bedside. A rollover valve should be installed prior to a filter you mentioned. However, factory filler neck have a fitting to allow air displaced during filling, a place to go. This operates the aspirator tube to shut off the pump and helps reduce the interruption of fuel flow when refilling. I would recommend a period correct carbon canister, when “Tee’d” into your air line, can store & save the hydrocarbons you paid for. Using a vacuum switching valve that opens when coolant is at operating conditions, the engine will evacuate the raw hydrocarbons and add to fuel economy. A late model canister can be adapted from a salvage yard and mounted underneath out of sight, but the folks using an “LS” type engine can be programmed to operate purge only thru one hose. No EVAP software needs to run. If you don’t give a captured place for your tank fumes to go, like a canister, you will smell raw fuel sitting still durning ambient temperature changes. The fuel heats up while driving from road heat, exhaust and any engine that uses a return fuel line, from the injector rail, regulator type fuel filter or mechanical fuel pumps that have the return line. Just something to plan for as every project is different. Nice products at Brothers though. Research & plan helps.

Thank you. I was thinking of doing this to my 71 C20 but I see that it will interfere with my custom bed and bumper.
Bought this new and been driving it with the tank at my back till now, a couple more years won't hurt.
Buy a top fill tank instead so you don't have to modify your custom bumper and bed setup.
I’m impressed
Thanks!
For us lazy people a follow on how to hide a filler neck would be cool. Thanks for the videos.
We're actually working on a kit right now for that reason. Keep your eyes peeled for a video here or product release on our website.
Yes good idea maybe both ways.
@@BROTHERSTruckPartsTV any update on this? We are all ready to order haha
@@SLVRownr R&D on the kit was paused because of our recent move to Bowling Green (Aug 2022). R&D should resume early in 2023. Thanks for asking!
@@BROTHERSTruckPartsTVAny more updates you could give good sir?
Well done video. Pretty straight forward. I wish you would have shown one of your products for the filler opening. I’ve got to do low budget so that would probably be. In the wheel well correct? Thanks again for the great demo!
We don't currently have a filler option available for the side fill tanks. We're working on something that will be available by the end of 2021, but right now you have to do something custom to fill these tanks.
Thanks for another great video!
Do you have any videos showing the finished filler tube and call the the slide and center filler tanks?
Thank you
Thank you for this installation guide, went very well on my 72 GMC. What is the capacity on this tank though? It does not say on the website.
It's roughly 20 gallons.
Nice vid budy! Do you have any options for an easy replacement for an 84? I have 2 tanks one that wont switch over and one that just needs a replacement. Was thinking about going with a cell in the bed so I wouldn't have to remove the bed and I could just drop the tanks. Looking forward to any help you got.
This is our Rear Tank option for the Squarebody trucks. Link: www.brotherstrucks.com/73-87-GAS-TANK-UNDERBED-ALUMINUM/productinfo/ATK7387/
Question about cutting the bed sill...did you cut the wrong side of the sill?? I ask because if you flip that sill, thats how its mounted to my bed and how it sits on my frame.
This is awesome do u guys have an aftermarket tank like this one for a 1950 Chevy pickup? I just finished my 6.0/4l60 swap I need to install the gas pump inside the tank, thanks guys.
J P yes they do my friend
Excellent thank u sir
I hope brothers will offer their own version of the tail light fuel filler door assembly.
We are working on one right now. No details on the timeline for a release, but it is definitely in the works.
@@BROTHERSTruckPartsTV thank you. Bought the blazer tank . Then like most people think , I was like okay there has to be an easier way to put the fill neck without too much fabrication. So a bolt on brake light flip lever would be the best option for the blazer tank.
What are the options for the vent outlets and return lines do they make caps to block one side over like on filler neck side I would like to see a video on installing the fuel line filler/vent install im sure they there I just can’t find them
Great video. I am interested in swapping my gas tank for one of these side-fill blazer gas tanks. I have seen a couple videos of the installation of the tank itself, but I cant find any videos of what people do with the filler. Does anyone seen a video of people actually routing the filler on one of these tanks. Thanks
Maybe it depends on where you get your tank from, mine is from LMC, but i can't slide my tank far enough back to be able to move the fill neck behind the floor sill so what i have to do is cut it off and move it back at least 2". Does it make a difference from a steel bed to a wood bed? From what i can see this is a wood bed.
Doesn't matter if it's a wood bed or steel, same sill positions for both. We don't know what tank LMC offers, so it's difficult to be helpful with your fitment problem. Best we can do is show you that ours fits and how to install it. Maybe you can watch our vid and compare what your tank looks like to what ours looks like.
This fuel tank conversion is one of the projects that I have on my list.
Question, at the 5:11 mark, instead of cutting out the notch in the frame, why couldn't you take a torch to the area and hammer it down to make clearance? No material is removed, thus maintaining structural integrity for those of us who have the optional leaf spring suspension.
That's an option for anyone who has a torch available and is comfortable creating a clearance notch that way. We are just trying to do it the way we assume most people watching the video would based on standard garage tools. Thanks for the comments!
Finally after two years I have a tank kit on the way. Can't wait until it arrives so that I can check it out. Of course it'll still be some time before I install it, I'm still gathering parts before I tear down my truck.
Do you have any videos or options for 1965 and routing the filler behind the tail light? Is it possible to put some type of hinges on stock light or do I need to replace with some sorta kit
65's are pretty tight behind the tail light. We don;t have a kit for that specifically, but we are working on a kit that will allow you to fill the tank from the bed pocket.
Just received my tank! Curious if there's any benefit to running a thin strip of rubber along the outer-flange of the tank to provide a barrier between metal on metal.
There's certainly no disadvantage, you might as well try it and provide us with some feedback! great idea!
I have a 70' Chevy C20 longhorn and it was converted to propane at some point with a filler door on the passenger side. I will be converting back to gasoline soon. Is it possible to flip this tank around to fill it on the passenger side and keep my current filler door?
We think that's possible. Quite a few trucks came with dual tanks, so you just need the parts from a donor truck to complete your project.
New sub here with a question. Will this hinder lowering the truck?
Not unless you are planning to set the frame on the ground. Most standard drops will be no problem at all.
what’s difference in side fill vs top fill. i put a side fill in mine and didn’t know if there was any reason to switch over ? i was wanting to keep my filler hidden but can’t find a decent spot or way to put it in
The only difference is where the fill comes out of the tank. We're working on a couple solutions for the side fill tanks that would make it easy to place your filler neck and keep it relatively hidden yet still convenient to fill. However, those won't be available 'til mid-year 2022.
@brotherstrucks will the 63 blazer tank work on a 61 Apache camper special?
It won;t work because of the frame width on the '61. However, we offer a tank that will work on your '61 but it's an aluminum tank. Link: www.brotherstrucks.com/1960-62-CHEVY_GMC-TRUCK-GAS-TANK-UNDERBED-ALUMINUM/productinfo/ATK6062/
Could you make a " How To " video on how to hook up 2 fuel tanks with one pump? I own a 87 Chevy V20 6.2L diesel and I am looking to add a 20 gallon plastic/poly auxiliary fuel tank on the passenger side of my fleet side bed which already has the hole and door in the side of the bed. Basically my truck bed that I bought was set up for 2 tanks
Providing that your fuel pump is outside the tank, you could just use a basic tank switching system. Many types are available from super simple manual valves, to more complex electric systems that will switch tanks as well as fuel gauge input etc. A quick Google search on the subject will get you more info that you probably need.
Where exactly did you run the vent hose you mentioned at the very end. The only problem I'm having with my install is that it's not venting properly, making filling a pain. Can you recommend a vented filler neck that might work with this setup? Thanks.
We ran the vent along the top of the frame to about a foot in front of the tank. Not sure what your current filler setup is like, so it's tough to recommend a vented filler to take it's place. Where is your gas fill located now?
@@BROTHERSTruckPartsTV mine is installed about half up the rear fender on my step side. I'm considering either retrofitting a vented fill neck or running a vent tube along the fill tube with zip ties and then putting a rollover valve at the top.
@@JeffLarkin Try the vent tube and zip-tie first, if it works for you then you can eventually upgrade to a vented neck.
Will this be a direct bolt in replacement for my 1964 GMC carryall (suburban)
No sir, it doesn't mount the same way as the original tank. You can use it, but it's not a direct replacement.
I put a 65 corvair body on a 95 s10 frame. Using a blazer gas tank where the corvair motor use to be how much clearnce is there suppose to be around the gas tank or should I use thick rubber.only have a 1/2" clearnce around tank.
1/2" clearance should be fine.
I have a 64 c10 that I plan on installing bags and a bolt in c notch. Will this tank work for me or will I have trouble with ground clearance?
You'll be fine with this tank.
On the side where you start drilling the strap holes through frame is the bolt going to be through frame then tank and then straps ?? Or holes only for straps and you put different bolts through existing holes on frame to hold tank to frame??
The straps hold the tank to the frame, none of the bolt go through the tank flanges. So the straps are anchored at one side and then attached by the "J" bolt on the other side then tightened into position.
Cool .. 👍🏼👍🏼thanks !! Hope y’all had a good thanksgiving!!!!🦃!!
I building 72 G10 dropped it cut 1/2 off coil spring ,
We’re do I find best sway bar kit
Sorry, we don't do G10 stuff so we can't recommend anyone for sway bars. You could try PerformanceOnline.com and see if they have any.
The only concern I would have is notching the frame if you intend to carry heavy loads, maybe welded supports in that area?
We've never had anyone report a problem.
@@BROTHERSTruckPartsTV Just was wondering thanks
Is there any reason the straps could be eliminated and just bolt the tank directly through the flanges? And do you need a thin strip of rubber between?
You could do that, we've done it. It just makes it easier to remove and replace with the straps. Yes, use a thin insulator between the flanges and the frame, rubber would work.
What if bolt’s didn’t come in my kit? Where can I buy the strap bolts?
Does this tank need painted to prevent rust or is it coated already?
It's coated
Mr. Welch. Is there a change in fuel line size, or a difference between 3/8 or 5/16? Should the fuel line size be changed?
That entirely depends on the needs of your engine. Most engines will operate just fine with 5/16 fuels lines. Engines with higher horsepower will require more fuel and therefore also larger lines. If we were to draw a line where 5/16 was no longer enough and 3/8 or larger was necessary, we'd say that happens at around 400hp.
@@BROTHERSTruckPartsTV Thank you, and thank you for the great video's.
do you have the measruements so i can check if it fits my 68 d100 sweptline
Call our office at 800-977-2767 and they'll be able to help out.
Any chance you have a tank that will fit my 72 Chevy Van? Hard pressed to find one.
Not certain about van fitment on any of our tanks. Sorry!
How would you run your exhaust through the back of the truck?
Can you do this with a 80s C10? I want to do under the bed tank but retain the side fill door on the drivers side of the bed
@@BROTHERSTruckPartsTV I wanted to have the tank centered over the rear end for better traction.
@@SamuraiCommando Here's a link of our custom tanks for the Squarebody, There's a couple options that will do exactly what you want. www.brotherstrucks.com/Custom-Gas-Tanks/products/2509/
Since he's installing a blazer gas tank on a Chevy truck, can I install the 82-86 year 25 gallon blazer gas tank on my 85 Chevy to get a side inlet rear mounted gas tank?
Good question, but we've never done it so unfortunately we don't have the answer either. In theory it's sounds like it might work? It's going to depend on how similar the rear of the frame is between the Blazer and the Truck.
Do you have any photos of the finished truck to see how far the tank hangs down?
The guys at the shop may have something to illustrate it. To be honest, it doesn't hang down much further than original spare tire would.
what kind of filter do you use on the vents?
Is this a full-size blazer tank? Would an s10 blazer tank work?
No idea, never tried that conversion. Sorry!
I bought a 1972 c10 stepside not long ago and I really wanna do this to it I just don’t know what all do I need I been looking a different website but on the kits it only shows straps and sending unit I don’t find where do I get the new lines and the nozzle and cap to place it on the side field can some one please help me out I sure will ethanol you for this video it helps a hole lot
running new lines is as simple as extending the existing lines back to the new tank. If you're adding a side fill, thne that becomes more of a custom project you'll need to work out on your own. Figure out where you want it, what it should look like and how easy it will be to fill... then do your own mods to get the pipe to the tank. Not really that difficult, just requires some planning because there is not a current kit available.
BROTHERS Truck Parts thank you for taking the time to respond I will take some time to make a drawing to see where I wanted thanks
My 17yo son bought a 72 C10 that he wants to do this conversion. The previous owner had this side fill tank but he had cut out the cross member that the tank goes up next to. We have looked all over and can not find one and it appears that no one reproduces this part. Do you have any suggestions on where i may be able to find this cross member?
When you say crossmember, are you talking about a crossmember that supports the bed, or one that goes side-to-side in between the frame rails?
@@BROTHERSTruckPartsTV the one between the frame rails that the fuel tank would go closest to.
@@droark2 That's what we thought... Unfortunately you'll have to get one from another frame if you want to replace it. It's possible that if it's been out a long time and hasn't caused an issue, then you could just leave it out, but that crossmember is supposed structural providing it wasn't the one that normally supports the spare tire.
BROTHERS Truck Parts that’s what I thought. Unfortunately I’ve exhausted my area salvage yards and none of them have anything this old. We’ll keep looking. Thanks for your time.
So I'm just starting my project but want the filler behind the rear licences plate .. is there a option for this or do I need to have it moved..working on 67 GMC
You can't do it, the filler would be below the tank and the fuel would have to run uphill. There are other options, but behind the plate isn't one of them.
@@BROTHERSTruckPartsTV didn't the old impala's and Chevy nova have them behind the tag🤔
th-cam.com/video/_JjVi5rfID8/w-d-xo.html I was correct the 71 nova had it out behind the tag.
@@gadgetmanhookup They did, but those tanks sat significantly lower and were much more shallow than this tank.
@@BROTHERSTruckPartsTV do you sell a hidden hitch that would be accessible behind the tag, to work with this tank?
I have a 1964 GMC C -10 305 V6 3500 does anyone no if there's interchangeable parts like suspension,brakes any upgrades to modern parts. Is this truck rare.???
Will this tank work for my 56 3100 ?
This one will not, but we do have a tank that works for your '56 here: www.brotherstrucks.com/Custom-Gas-Tanks/products/1596/
Which bed support needs to be cut. And what are the measurements for the cuts. I have a steel bed and want to get the cuts right the first time
The first support from the rear. It will be the one that runs directly over the space where the tank will go. We center the support/cross sill on the frame and mark it at the inside of the frame rails. Then, we cut up from the bottom leaving only about 1/2" remaining of the top of the sill as shown in this video.
I want to see how it was finished
There are so many possibilities it would be impossible to show them here. It's really up to you to get creative and decode how YOU want to route your filler.
Can I put that tank in a 77 frame rails Chevy C 10
Can I put that taken and 77C 10 Chevy pick up
so were the other little inlets just plugged off?
Whatever you don't use you plug off.
@@BROTHERSTruckPartsTV so can I just use the one vent beside the filler neck and just plug off the others?
@@kendrickbannister5025 Yes, unless your particular system needs another vent for some reason.
@@BROTHERSTruckPartsTV ok thank you.
What kind of filter should I put on the breather hose?
A small universal fuel filter like what is used on a dirtbike would work fine.
Here's what I used. Just make sure you mount it above the filler neck. I mounted it between the the outer and inner skin of the bed vertically on a piece of angle iron and fastened it with some bolts through the inner wall and painted over it. Nobody will know it's there. It's tucked away from any weather and water and you can still access it from underneath. The vent is designed to allow your tank to breath as fuel is entering the tank and leaving during fuel consumption. The valve also is designed to contain the gas in the tank if you ever roll the truck. All modern vehicles have this safety feature.

I purchased this tank for my 71 GMC short bed along with the in tank fuel pump kit from tanks inc. will this work with this tank or only top fill tanks which are more flat? Hope I hear from you guys soon. Don’t want to ruin this tank and have to buy another one.
We can't be certain it will work because we don't know the specs on the Pump from Tanks Inc. You're probably going to have to find the flattest place to mount the pump and then use a Body hammer and dolly to flatten any uneven surface, that's what we've done in the past. Check out this video we made installing OUR Pump in a top fill gas tank and it might help you answer this question: th-cam.com/video/79AP-e_ns_Q/w-d-xo.html
BROTHERS Truck Parts thanks! That’s the pump I bought from you guys. Still not sure where to cut the hole for the pump since the tank is different. I’ll figure it out. Thanks
Where do the fuel pump install?
That depends on your setup. If you have a carburetor then its likely you would be running a standard engine mounted pump. For Fuel Injection we offer an in-tank style pump.
What gallon tank is this
21 gal
Same kit for a 62 ?
We have a kit for a '62, but it is not the same as this. The '62 has a completely different frame than the '63+ does.

How do you access the left bed retaining hardware by the filler to bolt the bed on after the tank installation?
We've never run into an issue with that bolt. Please call the shop and we'll give you a number that you can text photos to so we can help you sort it out.
Is there anyway I can get a tank that can be under the bed and still fill from the cab?
That would be completely custom and something we've never seen done before. If you try it, let us know how it works out.
Curious if you did this and if so, how you routed the line from cab fill location to tank?
@@russellzacharias3535 Currently the plan hasn't started yet but when I return home from leave I can start thinking of how to do it. I may end up cutting a hole in the bottom of the cab to allow the fuel through to the tank. I reaaly like the look and ease of filling the truck up at that spot so If it works that'd keep her stock as well as functional
@@ethancotter4632 Ya, see that is what I was wondering...if you go out the bottom its going to have a point that is quite low to fill the tank (height wise I am thinking of various side mount GM pickups over the years and where those fill doors were located)...if you go from the original height and go back, through the rear of the cab you end up right close to where the bed walls are BUT there maybe room inside the outer skin (again its a height thing, wanting it down hill).
@@russellzacharias3535 Im sure I will figure it out, I need to see my options for tanks and spots to place it. I may be able to place it above the drive train. Though its not my first concern yet
What is the price for the tank?
These tank kits are currently $220 (8/22/20). There are links to the tank kits in the video description above.
@@BROTHERSTruckPartsTV ok thanks
Why not lower the tank rather than cutting the bed rale?
You'd have to lower it 6" or more to clear the frame. At that point ground clearance will be a serious problem.
@@BROTHERSTruckPartsTV I only had lower it 2 inches to clear the frame. We must be talking about different tanks. I believe I ordered the one I have from LMC five years ago.
@@BROTHERSTruckPartsTV in addition why would you lower 6 inches or more? Dave only cut a couple of inches out of the bed support rail in order that the bed would fit over the tank.
