You guys interested in this swap,

I used all pre-existing holes on the frame, except for the two I made on the rear cross member for the two bolts.

I started up my motor, the fuel sending unit works at least up till this point.

I'm liking it alot, except for one thing...When I nail it off the line, is any fuel going to leak from that neck & cap?

[Rudy-g]

I am actually going to use a newer fuel cap assembly i picked up at a junk yard I'll post some pics.

A friend of mine suggested fixing the filler neck so that you can fill it from inside the bed, If I have any problem with fuel leaking out, I might route the filler through my bed.

The member whom I got this idea from, says hes happy with his setup, although hes not running EFI and has a nonvented gas cap.

Something else one could try is fuel cell foam, maybe?

94-96 impala tank is 23 gallons the chevelle tank is 20 gal.

I didn't know that those cars filled from the back. I've got mine setup, it works and very affordable.

I'm thinking about a second build, so I'm going to research this impala tank.

Concerning the 94-96 impala tank (and not to hijack this thread)

I think the impala tank has a big hump on it. Seems like the chevelle guys just cut a hole in the trunk to make room for the hump

http://www.chevelles.com/forums/show...=123036&page=2

seems like from Rudys pics, there might be room up in the frame to accommodate the hump. im going to a junkyard this weekend to try to pick up one for my 5.3 swap.

didnt mean to hijack! this is a great thread!

$180 Motor mounts
$125 trailblazer ss exhaust manifolds
$85 ECM reflash
$550 chevelle tank, tank straps, fuel filter, high pressure fuel hoses and fittings
Feeling of accomplishment pricele$$

I am curious as to what straps you have holding the tank on? I got 2 straps with mine and they aren't going to work....

[Rudy-g]

I bought some flat stock steel at the hardware store; they are 2"x36" I paid $7 a piece, and I also bought two 1" angle iron $5 a piece

And I used the ones that came with the tank

[Rudy-g]

finished the tank install, I painted the gas tank with POR15 silver color paint

So about how far is the tank from the bumper?

[utee05]

I assume that those who go this route that you will not be using a hitch? I love this idea of filling behind the license place but on the off chance I end up getting a hitch I may be hindered.

Does anyone know how he connected the flat stock to the frame? I see 2 bolts holding each piece of flat stock to the frame, but I can't tell if he welded them to the flat stock, or used a bolt through the flat stock. I feel like a bolt through the flat stock would cause an indention or possibly puncture the top of the tank.

Thanks. As I mentioned in my post, I can see that he used flat stock and that he used bolts to connect the flat stock to the truck frame. What is unclear from the pictures is if the bolt head is under the flat stock or if it is welded to to the top of the flat stock.
