I`m going for a LM7 swap in my 77 c10. It`s a returnless style engine. I would like to use this setup for my project, but som questions: - What sending unit do you use? And how do you hook it up? - Due to the returnless system, do you mount a corvette regulator between the tank and the fuel rail?
You would use the stock sending unit. The pump will be placed elsewhere in the tank away from the factory sending unit location. As far as the regulator, the Corvette C5 regulator is perfect for your return-less system. That's the same one we use all the time for this conversion.
I have dual tanks and would like to start preparing for an EFI system. Wouldn't the existing switch in the cab work to select the pump you want to use? By what has been said it seems you are suggesting you would need a tank selector and another switch for the pumps.
It's really going to depend on how you wire your specific setup. Not familiar enough with the factory switch to say whether or not you could have it switch the tank and pump power at the same time, although with proper use of relays, I don't see why you couldn't make it work that way.
The pump should be more or less all the way down into the tray. The fittings should be whatever size your fuel line is, some is as small as 1/4 in, but we've seen people run as much as 1/2 in. Size the fitting appropriately for you lines.
@@BROTHERSTruckPartsTV I just hope I didn’t put the pump too close to the tray as to interfere with the pumps ability to pick up fuel. We shall find out in a couple days
Hi, very detailed video thank you. So my question is, the fuel pump that comes with the kit what psi is it running? do you offer a 7-9 psi version, my c10 is carburated is the reason i am needing this range
What external fuel pump kit would you recommend for a 67 C10 with a 6.0 LQ4 engine making about 540 HP. would like to get that 600HP one day. Thanks in advance.
We don't have recommendation for that. Check the offerings from Holley or Summit Racing. We're sure there are many options, our concern would be noise with the external unit, but maybe there is an internal option available which would make it MUCH quieter.
Why not just use 2 long threaded rods to hold the bottom piece up and then pull up and put all the final (small) bolts on and at the end just pull out the two threaded rods?
Those are both great options for a gas filler, but unfortunately we don't have videos for them. We'll take the suggestion and add it to the list for upcoming videos!
What specs are you looking for? We have multiple options, 190lph, 255lph or 400lph. They all fit 6”-10.5” depth. If you need any additional info then you should call our shop at 800-977-2767 and ask the customer service guys to help you out.
Didn't your kit have a pigtail hanging down from inside the top plate of the pump? That pigtail connector just plugs into the top of the pump. Please call our Customer Service Dept. at 800-977-2767 if you didn't have the pigtail attached t the pump bracket.
We don't see why it wouldn't work. You would need to install a pump in each tank, then switch power to the proper pump when switching tanks. You also have the option of running a single external pump and maintaining the same tank switch you have now.
Did a little more digging on this subject, here's what we found... This can be done on ANY tank that has a flat enough surface on top to mount the pump on, and a relatively flat bottom.
@@timothykeith1367 This is a custom install for those tanks that don't already have a baffle and pump for Fuel Injection. A TBI tank is more or less ready to supply enough volume and pressure without cavitation.
do you finish your build? I did a 73 C10 Instagram is @ ls_swap_sd but I used a fuel tank from a 87 throttle body truck w aeromotive fuel pump. Way easier and still cheap
Whoop whoop, 1974 C10 build. Now I can go full EFI.
Thanks for the videos, they are a huge help for my 72 C10 build!
Thank you!
Our pleasure!
What type of 4.5” hole saw did you use? Link?
Just one we picked up at Harbor Freight, nothing fancy.
Will this work on an original 1948 chevy truck side fill tank ? I'll be installing a 350 fuel injection engine.

How far from the bottom of tray should the pump be? I may have screwed up. That and what size fittings for the outlet and inlet?

@@Roadglide911 You should be fine. We press ours down right against the bottom too.
My fuel tank is only 5 and 1/2 in is there a way I can modify that to fit in my tank for my LS swap
We installed one in a 1960 Cadillac tank that was only 5 1/2" deep and it worked perfectly!
@@BROTHERSTruckPartsTV thank you so much that was a big help
Hi, very detailed video thank you. So my question is, the fuel pump that comes with the kit what psi is it running? do you offer a 7-9 psi version, my c10 is carburated is the reason i am needing this range
They are rated by "Gallons Per Hour", you would use a pressure regulator to adjust the pressure down to work with your carburetor.

I have a dumb question.. so after installing this aftermarket pump do you just plug the hard line on the sending unit? Since its no longer being used
Yep, that's what we do.
I have a custom stainless fuel tank that is 12.5" deep; do you have a longer kit?
This kit works with a 12.5" deep tank.
Would this work/meet demands of a Holley sniper EFI set up? Would be used in your 67-72 C10 rear mount top fill tank.
Yes and Yes!
@@BROTHERSTruckPartsTV would it work with the 21 gallon side fill?
@@dalecarmody8631 Absolutely.
Why not just use 2 long threaded rods to hold the bottom piece up and then pull up and put all the final (small) bolts on and at the end just pull out the two threaded rods?
Thats basically what we're doing with the two long bolts included with the kit.
Is there an option for a 70’s Ford pickup with fuel behind seat?
Sorry Bryan, we don't do Ford stuff so we have no idea what options are available
@@BROTHERSTruckPartsTV thank you
Great videos. Do u have a detailed how to video on installment of hide away taillight gas fill? Or through the rear wheel hub?
Thanks
Those are both great options for a gas filler, but unfortunately we don't have videos for them. We'll take the suggestion and add it to the list for upcoming videos!
Does the kit come with the pump also is the pump replaceable incase it goes out?
Yes and yes!
BROTHERS Truck Parts thanks guys
Does anyone have the fuel pump specs they use on their in-tank fuel pump kits?
What specs are you looking for? We have multiple options, 190lph, 255lph or 400lph. They all fit 6”-10.5” depth. If you need any additional info then you should call our shop at 800-977-2767 and ask the customer service guys to help you out.
Can I still run a LS 5.3 with out doing that with a external pump or no?? I have that same tank and thinking of doing a LS swap?
You definitely can use an external pump if you want. regardless, you'll still need a return line plumbed in somewhere.
Will the available fuel pumps pump enough fuel under pressure for a FiTech FI system?
Absolutely! One of the guys at the shop has one in his 1960 Cadillac with a Fi-Tech, no issues!
BROTHERS Truck Parts should have said a Mean Street FiTech FI.
@@Roadglide911 It will work.
Well you sold me. I bought one and it’s on the way. I have the same tank you used in the video.
@@Roadglide911 let us know if you need any help along the way!
What's wrong with rivet nuts?
They don't add any support to the new mounting point of the pump. Additionally, not everyone has a tool or knowledge on using those.
what I am worried about is the open electrical in the gas? should I be worried? or is that not a problem?
Most, if not all, new vehicles come with an in-tank fuel pump. The electrical connections in the tank are not an issue.
How did you make the electrical connections on the inside? My kit came with no connections to Make up to the under side
Didn't your kit have a pigtail hanging down from inside the top plate of the pump? That pigtail connector just plugs into the top of the pump. Please call our Customer Service Dept. at 800-977-2767 if you didn't have the pigtail attached t the pump bracket.
Would these work on a duel tank truck how would you switch power to each tank
We don't see why it wouldn't work. You would need to install a pump in each tank, then switch power to the proper pump when switching tanks. You also have the option of running a single external pump and maintaining the same tank switch you have now.

Can you run a after market frame pump to run a LS carb '86 SWB C 10 with dual tanks?
How deeps that tank? Blazer tank? Is it too deep for that baffle
The tank is 11" deep, yes it's a Blazer tank. The tank is not too deep for the baffle.
Can you used that kit on a 85 c10 gas tank ?
We have to assume you can, it definitely works on the early square body trucks up to 1979.
Did a little more digging on this subject, here's what we found... This can be done on ANY tank that has a flat enough surface on top to mount the pump on, and a relatively flat bottom.
@@BROTHERSTruckPartsTV How does that differ from the OEM baffle on the TBI square bodies ?

What wheels and tire size are those on the white and silver Chevy? Also thanks for all the informational vids!
What white and silver Chevy? We scanned this video but there's no trucks shown?
BROTHERS Truck Parts not in this video I apologize but a truck featured in the channel I commented on the latest video hoping for a response
Bummer, if you find it again let us know and we'll try to figure out the colors for you.
What brand is the pump?
It's our pump. www.brotherstrucks.com/1947-87-CHEVY_GMC-TRUCK-IN-TANK-FUEL-PUMP-RETRO-FIT/productinfo/FIPK372/
