I've searched through at least a dozen threads and cant find a definitive answer, so here goes.

I have a 1984 Z28 with the L69 which has a mechanical fuel pump on the block and a small helper electric in tank pump to prevent vapor lock. My gas tank has several pinholes and I'd like to get a new tank. It seems there are two types of tanks available, an 82-86 Non-FI tank (GM2721A) and 82-92 fuel injected.(GM2721B) As far as I know the only difference between the two is the addition of a plastic pan/baffle in the later fuel injected tanks to aid in preventing fuel starvation in hard cornering. The various sites selling the tanks specifiy w/o pan for the non-fi and w/ pan for the fuel injected.

My main question is, will my existing 1984 fuel pickup/sender/pump assembly work with the later baffled/panned tank or will i have to stick with the earlier style tank? The prices for the two are nearly identical so I figured I may as well get the "better" tank?

I'd really appreciate any responses.

 

Your set up, if the pusher pump still works, should work just fine in the baffled tank. Also, with the non-FI tank, it would also work since the pusher pump was retrofitted into the original carbed tank anyway. Just make sure the pusher pump works. if it doesn't, I'd get rid of it altogether or install an in-tank electric pump and bypass the mechanical pump which you can remove and block off. You'll just need to run a regulator. Since you're going to have the tank dropped anyway.

 

FWIW, I'm running an EFI pick-up & pump in an originally-carb'd tank. I haven't had any problems with this set-up.

I have a pristine carb'd tank I'd let you have for the getting.

 

After about 7 hours of work, I got it out.

Does anyone have a source or alternative for the antisqueak padding for the straps and tank? After 26 years the stock stuff has just about had it.

 

I haven't looked for it, and I haven't tried this, but I would think roofing tar paper would do the job. The heavier stuff.
