In this video I detail the removal of the fuel tank and impact bar from the 1991 Corvette salvage parts car. I explain how the C4 fuel tank/impact bar is mounted directly to the rear frame rails of the car and show the assembly method of the individual components and how they all come together as a complete assembly.

Thanks Oswald, glad to hear it was helpful👍.
Thanks this helped me remember there is a mounting plate between the impact bar and the chassis.
Hey Wally, glad to hear it helped you out👍.
Great videos dude........
Thanks Andre, appreciate the feedback. Have a great weekend👍.
Just did this today not to bad for my first time mine is a 1990 I'm 68 woman and my husband is 80
Excellent! Glad to hear you guys were tinkering on it. Just goes to show age is just a number👍
6:39 EVAP cannister
Yep👍
This video helped me a lot, thanks.
Henry, glad to hear that👍. That isn't the most fun job on a C4, at least now it's behind you.
Thanks for the video!! Very helpful!
No problem, glad to do it👍
thank you very much@
No problem👍
Awesome videos! I'm currently stripping down a 88 for a Bonniville build your videos are by far the best I've seen and very helpful
Thanks buddy, appreciate the kind words👍
Hey.. nice video, it saved me to looked how to change the feul pump on my first c4. Corvette,, thx man,,,
Thansk Oscar, glad to hear it helped you out👍.
good video, someday i hope not soon i have rusted fuel lines
Hey Mako, it's definitely an all afternoon kind of job.
What kinda bolts are the 8 on the sub frame to frame?? I can’t find anything
They're natural cast 15MM long thread bolts with a shoulder. From the factory they can be seen pretty easily, but sometimes cars that have aftermarket undercoating applied hides the heads of the bolts. Just look for the spot where the aluminum impact bar attaches to the steel frame rails and you'll see the heads of the bolts.
much appreciated
No problem, glad to do it👍
@@VetteSource I have an 87 here in Australia and perhaps i can buy parts from you ?
Sure, I can help you out. You can reach me by email - vettesource@hotmail.com
That's better than a Haynes repair manual.R.M.
Hah, I know what you mean. I always loved the disassembly picture on the back cover with the Corvette in pieces, but found the tear down and troubleshooting descriptions in the book lacking in substance.
I'm looking to replace the rubber fuel hoses that connect to the sending unit, is there anything special I have to look for when buying replacements?
Hey Joburg, just nake sure it's flexible hose specifically rated for fuel line application, and you should be good to go.
@@VetteSource Thanks for the advice and all the great videos. I just watched your videos on removing the rear bumper so I should be good to go once I get the right hoses.
Glad to hear my friend. Let me know.if you need anything else👍.
Is that other car a volvo?
Which one? There are a few there but no Volvos
I bought a C4 recently, and I learned lots of things from this video. There's no substitute for seeing the guts of a car in this way. Your commentary is great, too. Well done, and thanks!
I parted-out BMW e30 3-series cars for a while. I foolishly did that without a cordless wrench. Cranking old / often rusty bolts, in tight spaces, by hand, SUCKS!
Thanks for the positive feedback👍. Yea, tearing out chassis and rusted bolts with hand tools will make a broken man out of you very quickly😂. Its nice to have some "cheater" tools to work with.
Super helpful videos. Can you show how to remove the side panels from the C4 Corvette? I am trying to strip mine all down and don't see how to disconnect the hind quarter fender panels. I think others would like to see this also.
Glad to hear you enjoyed them, appreciate the feedback.👍 The one quirk with the C4's is that every body panel on the car is bolted to the unibody/chassis structure with the exception of the quarter panels which are still glued to the inner tube like the earlier generations of Corvettes. I will be making a video soon detailing the removal of the quarter panels on the 1992 Corvette convertible project. You can find the playlist here -

Can this be done with the rear bumper still in place?
Hey Sean, it sure can. I just had the rear bumper removed so you could visualize all the individual components.
Can the tank be removed without removing the impact bar , or is it easier to do it the way you demonstrated ? Great information by the way .
Yes, you can loosen the six mount bolts that tie the impact bar to the rear frame rails, and it will drop down just enough for you to pull the tank straight out once you remove the tank to impact bar retaining straps. Thanks for the feedback, appreciate it👍
Can the fuel-cell be removed without taking the tank and everything out of the car? Can you just pull the fuel-cell out from the top with out taking the tank out of the car?
If you are referring to the fuel pump/sending unit, yes it can. It is designed to be unbolted and pulled out from the top once the fuel door assembly is removed.
If you thinking of the inner plastic bladder that is inside the tank you will unfortunately be forced to pull the entire tank assembly out of the car like I showed in the video, although you will be able to leave the rear bumper cover installed during removal.
@@VetteSource I was referring to the fuel pump. Thanks, good to know.
NP, anytime.
where is the EVAP (Charcoal Canister) on a 92 LT1
It's mounted on the back right corner of the car attached to the aluminum impact bar like the one detailed in this video.
@@VetteSource i’m such a newbie when it comes to vette’s. when should i change it? how do i know i need one? i have 97k miles on it. are there ways or mods to keep water from getting in the gas tank?
Don, no worries, Corvettes are fun to learn about since they are complex enough to make then challenging.
I wouldn't worry about the EVAP cannister unless you are getting a strong gas fume smell around the back of the car. With 97K miles you should still be OK.
The best way to keep water out of the fuel tank is to make sure the drain hose located behind the fuel cap is not plugged up. Due to the location of the sending unit/filler neck, the Corvette engineers knew that water would get in there so that's why it has the drain hose. They just did a poor job of telling owners to check it to make sure it wasn't getting clogged up which can lead to water contamination in the fuel and destroy the fuel pump/sending unit assembly. Let me know if you need anything else👍
@@VetteSource Thank you so much! the only smell i get is just the old car gas smell! i just figure old car i smell emissions sorta deal. i guess it would be behind the vehicle i just figure the exhaust.
No problem, glad to help. If you're not already, I would suggest running premium fuel on your next fill up and then poking your head around the passenger side rear wheel to see if you get the strong fuel smell while it's running. Let me know if you need anything else👍
Are any of these parts for sale ?
Sure, what are you looking for?
@@VetteSource looking for an intake duct for an 1986 corvette part number Intake Duct - GM (14084404)
I'm also looking for a roof top. Mine is the acrylic blue top, but it is cracked.
@@tomschmitt6510 ok, yes I have the duct assembly complete with upper and lower housings available for $150
@@tomschmitt6510 unfortunately no targa roofs available at the moment.
That's no 20 minutes !
You caught me. Close enough for government work, though😁. Thanks for watching👍
How much money u made on those ads?
wait, you can make money off youtube?
@@VetteSource disable your ads please sir
you may not have heard, but earlier this year CZcams decided it was going to run ads on whichever videos they wanted, even if you weren't monetized. Unfortunately I couldn't prevent them from running on my videos even if I wanted to.
@@VetteSource I'm sorry that stinks
why you guys fixing these clunkers up for? I get it thats it a corvette but you can pick up nice ones for 5-8k. I have had 2 of them. Paid 5k for a nice 94 with 100k miles. another 95 6 speed for 6k. both vg condition. sell that one for parts and make more money than its worth.
I'm guessing you didn't bother to watch the rest of the videos in this series in which I dismantled this car to sell off as parts and make a profit exactly as you described. Thanks for the comments👍.
Oh God don't you dare give a custom that nasty old brake line always buy a new brake line.
You simply buy a line and bend it.
No, I only include them for fitment purposes. I don't recommend reusing them.
@@VetteSource oh
