I have a few of these trap doors available on my eBay store for those interested
They are a huge pain to assemble so I'm probably NOT gonna make more.

All of us third gen owner builders have to be very grateful for your channel!!!
Thank you
Yes you are right
100%
Cleanest trap mod I've ever seen. Insanely nice fit and finish. Well done.
I have a 4th gen z28 that I found with 180k miles on it. Most of the car was pretty ratty so I was VERY relieved when I discovered the fuel pump access hole wasn’t hacked into it. This is a super cool option that’s way cleaner than how folks normally do it!
This is precisely how to do this mod properly if it is something you want to do, regardless of whether or not you're replacing the tank.
The workmanship once again is 2nd to none! So nicely done....
Pretty cool work! Makes me happy to see a third gen get the royal treatment. Good job bro.
Another great video. I never understood the problem with this. Do people that complain about it also complain if you change mirrors or headlights? Modification for improvement is kind of the name of the car game imo.
It's super silly to rag against a clean fuel pump access door. I have welded in Sub frame connectors, cut battery tray for an intercooler pipe, battery relocation with a Moreso Cut off switch in my taillight. This is a Raceway and its done right and professionally (I'm a professional automotive technician)
I think it's more of the hack jobs many are used to seeing under the carpet.
the tin snips and duct tape horror stories.
@@3rdGenGuy Yep, original owner of mine cut all the way across the trunk to pull out the entire sender without dropping the tank, and then just threw some caulk on it...
@@3rdGenGuy Yes, agreed, done properly it looks and functions great.
@Crafty
The horror!
Thank you for sharing this video ! I just did the exact same thing, and glad I did. Structurally it feels so much better than without that 1/4 frame in there. Nice Job !!
The gas tank install was my biggest "re-occurring" problem, not for fitment, pump replacement, fuel lines etc. etc. but because I used a 4th gen plastic tank (works great) except, I struggled with a vent. It wouldn't take fuel well, gas would bubble bsck up and out the fill pipe. Gave large vent now, so it works however, have not found a vent valve / filter that is large enough to place at the end of vent line. Always something, enjoy your vids, Thanks
Now THATS the correct way to do this. Has GM done originally to these cars there would be no issue like this today. If you do install a trap door to get to your fuel pump, do it exactly like this.
Also, afterthought: this is NOT a chop job. A hack job is cutting up your car not know what the F you’re doing. Jobs like this are called design improvements.
Oh no! You did the trap door mod! The F-body gods will smite you! For shame!!! In all seriousness, I'm not sure why some people with sticks up their butts have an issue with this. If it's done cleanly (yours is one of the better examples I've seen) it's hands down an improvement over having to drop the tank. It SHOULD have come this way from the factory. I've done it on every Camaro I've ever owned and will if I ever buy another in the future.
This came out great. I'll be doing this to my 4th gen 93-97 Camaro and then sumping the bottom of the tank for a big pump when under boost.
I have 2 left as of 4-9-24

It would have been nice of GM to do this
Greetings from Torrance, CA! A few years ago I had to replace my fuel pump on my 89 IROC. I saw a lot of videos on how to cut a trap door and all of them seemed like hack jobs. I couldn't bring myself to do it, so I dropped the tank and did it the right way. But, the way you did it was very professional! You might now have a bump in the carpet( there are ways to hide that too) but the job was very clean. You got me hooked(even though I wouldn't do a trap door) and I subscribed. Going to check out your other videos! Thanks!
i was worried about a potential "bump" in the carpet, but it wasn't an issue.
@@3rdGenGuy i have heavy batting under my carpet....i will leave it in place around the trap door, but on top of the door plate i will remove the batting and glue the carpet cut out onto the door except for an inch and a half around the perimeter....so the bump is reduced, and all i have to do is fold back the edges of carpet to access screws
Unless its a trick of the camera or a mirror image it looks like your rotors are on backwards. The slot should draw brake gasses and dust outwards,yours looks to be oriented directing them inwards.
Great video! I used to own a 3rd gen Iroc and I LOVED it
different rotor brands have different orientations.
in the BAER case, it's a curved vein rotor and the slots face the front of the car.
Some other's are the opposite.
in Hellcats for example, they don't have a rotor direction since it's a straight vein rotor.
very good work,, the gas tanks are hard to get out,,man
Wait... didn't you tell people in your fuel pump video that if you cut the hole "I will find you!"? 🤣🤣🤣 At least this video is well done. Glad you finally saw the light. I like how you at least lowerd the tank so you won't have risk of hitting the tank. That's what I did. You did waste a lot of time cutting smaller and then bigger. There are a lot of threads on forums showing where you should cut. Also, the Allstar 14" x 10" fits very well. Unless you have a bone stock restored TTA, Firehawk or another rare 3rdgen, just chop ot up and make it better.
I wouldn't have bothered if my suspension was stock and easy top drop.
it's super annoying with all the coilovers and canisters in the way
Super clean setup! Can't wait to do it in my 92 RS.
He had to do it because he replaced stock with the aeromotive that sits higher on the top.
It's only controversial if you death wheel it out and just duct tape it back in.
This is just prudent.
I have to say im not a trap door fan but this looks excellent and almost factory great job!
I remember when you said if you cut a hole to access your fuel pump, I will find you 😂. Looks good tho man 😎
Everybody should do this screw keeping it orginal even if you have a mechanic do it its much cheaper in the long run
A fuel pump access door would be a nice feature, but is useless without quick disconnect fittings to the fuel pump, which I noticed you had in the video. I have seen access holes cut with an exaggerated L shape to remove the factory hard lines or the hard lines were spliced backed together with rubber hoses and worm clamps.
great job, my Camaro doesn't seem to like my stick welder that much.
that metal is super thin. it's like 13 gauge steel.
I can imagine using a stick welder would be a nightmare.
It's funny your video replacing the fuel pump the long way and you saying do not cut the trunk I will find you played right before this one😂
I saw your thumbnail, and couldn't believe it! LOL congratulations for joining the rest of us Neanderthals.
i saw the local 77 logo on nates welding mask & instanly subscribed
gave him some weld practice!
since he's all about that CNC life now.
between you and badluck Garage, i got my car going right. i also did holley terminator x. with a 4L60 if you have any questions lmk.
Very well done. I've been thinking of doing this. I'd only do it if it looked as good as yours though.
I love this guy.
Mine was already cut out...lifesaver
march 28th 2020, "if you cut a hole in your trunk sheet metal,I will find you" i guess you didnt keep your word, anyways two are still great videos
have you seen the holes people cut?
@@3rdGenGuy some of them yes, but I will never do it, I rather drop the tank
clean hole with a nice door=good
giant hole with self tappers and RTV=bad
@@3rdGenGuy i think i looks way better then the others i seen.
Now it just needs a salvage title
That looks beautiful 👍
WOOW 😮 FANTASTIC WORK ❤
I'm wondering if some sort of seal between the two surfaces might help with fumes leaking in the cabin? A rubber gasket or something? But that's just what I wonder. What I know is that you did this absolutely the right way, no doubt about it.
it's very flat with tons of bolts.
I doubt anything will get though, especially with the gas tank shielding it as well.
It f ING sucks that gm made it a pain in the ass to replace yhd F uel pumps on these 3rd gens
I can't believe I have to say this, but:
DO NOT weld above a gas tank that is full of fuel.
Some people seem to be confused so this is the clarification.
full gas tank + welding 1/2in away= fire.
Nice work.
If you’re willing to drop the tank, why bother with the trap door?
500th like for this video!
Good job but didnt see the part where you hooked up your lines before you bolted the cover on.
it's an aftermarket sender. it's labeled IN, Return, and vent.
Any chance you'll be making more of your custom trap doors? I am in need of one.
I'm trying to get another batch done.
waiting on a friends CNC machine to get up and running
I pushed in on mine with my middle finger and it rings like A drum.
And mine bird is a 66k 83 lg4 t5.
Great shape!
Thinking about a holley two barrel
Tbi and some highway gears.
Got some questions: I just picked up a 1991 Firebird 305 TBI. I don't have a key for it. The car was sitting for 12 years and is in very rough shape. The engine was locked up. I got it unstuck by soaking the cylinders with PB blaster and ATF. I attached a remote quick start switch directly to the starter. The engine turns over just fine but isnt starting with starter fluid.
Should it fire up temporarily with starter fluid? Or do I need a key? Or is there a spark issue?
a 1991 is gonna have a VATS key, so you'll have to bypass it.
I have a video on it.
since you don't have a key, you'd have to test all 10 resistors and see what works.
not hard really.
there are also VATS bypass boxes for like $40 that have all the 10 resistors built in

Nice
Can I just use a pneumatic sheer rather than taking the tank out? I don’t really want to drop my rear end 😅
if you have room for the tool, sure.
but the oem lines will have to be cut because they can't be removed without dropping the tank.
Hey guys quick question from a mechanic with a newly purchased gen3!. I bought the car with a bad fuel pump. And it sits outside my shop. I want to do this in place to get the fuel pump access, is there enough clearance to do a surface cut without plunging and if so what are the measurements for that? Lmk. Thanks!
You can cut with the tank installed, but it's risky.
plus the OEM lines are very long and makes it hard to access without dropping the tank.
Just cut the carpet. Carefully. You dont want to have to break your fragile antique panels every time you go digging back there. Then hot glue some velcro seams around the cut edges.
Wait... YOU!?! WHAT!????? Lol. J/k man. Good job as always.
Very clean install, as always.
Are you running the aeromotive 340? Was thinking of getting that same hanger set up but swapping in a 450 to keep up with boost.
it's the 340LPH pump.
Aeromotive says it's good for abut 600 horsepower.
plenty for the engines I'll run
Nice install, too bad the factory didn't do this.
❤❤❤
Was that an original replacement tank I assume?
yep, I have a Doorman replacement tank and a Aeromotive sending unit.
but my trap door works with OEM sending units as well.
@@3rdGenGuy - Cool, thanks.
Where did you get the sending unit from
Aeromotive 82-92 sending unit.
it's NOT cheap though.
Is the sending unit location on the aeromotive tank in the same place as the factory tank?
yes, because the tank is just a stock replacement tank they had painted.
@@3rdGenGuy oh dear god i just about had a heart attack when i saw this comment....i didn't know you replaced your tank, good thing it's in the same location (wiping sweat from brow)
Do you have the STL File you made for the resize trap door?
I do.
shoot me a PM on Instagram (@3rdgenguy) and I'll email it to you.
What sending unit is that?? Can 2 fuel pumps be put on that??
it's an Aeromotive gas tank.
You'd have to call them about dual pump support.
my tank has a 340lph pump, so good for about 600 horsepower
I didn't wont to cut my 86 TA WS6 to get to the fuel pump but whatever. So I removed the carpet and the hole was already cut. Problem solved. I'm at peace with myself now.
Why didn’t the GM executives just make a trap access door to the fuel pump when the damn car was built in the first place?! …and this is why the makers at Toyota are way above & beyond the rest
has to do with the crash safety requirements of that era.
that gas tank area is a crumple zone
Cost..they sweat costs to fractions of a cent.
no gasket? 🤔
You can add one If you want to
What size of tires you got there
16in stock wheels use a 245/50r16.
but my race tires are a 315/30r18
I would never cut up my GTA Trans Am
I would never cut up my standard Trans Am.
so be it, enjoy dropping your tank every time you need a new pump or sending unit
Awesome job!! I've finally met my match when it comes to being anal retentive! I have an 87 GTA that I've been wanting to do this to for years, but I don't have a nice shop like you have, don't have a welder and don't know how to weld anyways. Would be great if you could give the measurements for where you drilled that first hole, that would save all of us who wants to do this a lot of time. Thanks for another great video!
i cut my detroit speed door down to 8" wide and left it the original length. @14.21 there is a good shot in the video of were to place the base plate....there is a half rib indent in the floor pan that stops about an inch from his plate (on the bumper side) i moved mine to cover the end of that rib by about half an inch so it doesnt cover the bottom of the fuel pump hat
Anal… why not mount/ weld the threaded ring under the floor sheet metal?🤔🤪.
That might just be painful and tedious!
So the problem is with this mod is its a safety hazard. If the car ever hits hit in the rear, that is now a major weak spot and if the tank gets ruptured, now it has a way into the cabin. The "trunk" area is designed as a crumple zone. You should have seen the donor Camaro I got parts off of that had been smashed in the back, there was no back seat it was hit so hard.
This info is from GM engineers that helped design the 3rd gen Fbody.
Ur logic is flawed there.
yes the rear is a crumple zone.
but it's also where the gas tank is stock.
my trap door made that area stronger not weaker.
it's 3/8in of metal where the 0.090in thin factory metal was.
@@3rdGenGuy Yeah. Just can't get away from the "safety Police". Saving the world from destruction. Where would YT be W/O them?
@@3rdGenGuy you tell him, i was thinking the same thing....how the hell does it get weaker with thicker metal...lol
