Tips on gas tank removal? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

kxmotox247 · 09-07-2004, 09:08 AM

I'm going to be pulling my in-cab gas tank this week and was looking for tips or advice on doing it. I'm going to try to siphon most of the gas out before I do it. Any tips or advice on doing this? I want to insulate the back of the cab with some dynamat for noise reduction.
Thanks,
Josh

It's real easy. Just remove the seat, and then all the bolts around the tank, (i think there is about 6 0r 8) then the sending unit wire, and then disconnect the fuel line. You may need to push the fuel line forwars slightly before the tank will come out. Slide the tank towards the pass side first with the fill cap off. Then when it comes through the grommet on the side put the cap back on.
Good luck!

Oh. and keep an eye out for the build sheet behind the gas tank. Make sure you save it if you find it back there.

I forgot that there might be a build sheet. There is no sticker in the glove box and I've been wondering what was on the truck from the factory.
Sounds pretty straight forward.
The only other thing I had a question about was that my seat doesn't fold forward. I didn't realize that some seats were "fixed".

I hope it's worth insulating behind the tank. The road noise coupled with the exhaust is out of control in this truck.

By the way....thanks!

If you soap up the grommet around the fill tube it will come through a lot easier.

Make sure you run it dry also. A couple gallons of gas moving around does not help.

I siphon what I can, the drain the rest into a 5 gal bucket. And be sure to smoke while you're underneath draining what's left in the tank.

You do have good insurance, don't your.

Thanks for the good tips. I might get started tonight.

Anyone have any good techniques for siphoning?

Yeah, use of a siphon pump is preferred, or have one of your teenagers do it.

I pulled my tank last night, there were 7 bolts holding it in. I greased the filler tube a bit and it didn't give me any trouble.
The vent hose running up the side of the cab can be tough to get out. Here is the method I used last night:
Pull on it, realize it's stuck and won't come out. Try to bolt it back in, figure out that you moved it down and can't get the bolt in. Push it up real hard trying to get the bolt to find the hole, hit your thumb on the sharp cab edge and cut the he!! out of it, when you are done cussing realize that as a reaction to getting cut you pulled the vent tube out, and it's now laying on the cab floor.

Now that sounds like fun, at least you don't have to put it back.
