I am just gathering parts/information to prepare for my LT1/t56 swap into my 89 TBI T5. I have a complete 1997 donor car. I am on a pretty tight budget and I am just wondering what my best bet is for fuel delivery. The original lines are not in good condition and I would like to replace them.

Can I use the LT1 fuel pump/sending unit in the third gen gas tank? Should I just swap the whole tank? Where is the best place to get affordable fuel line?

Thanks for the help.

 

As far as extreme budgets go, you actually have a couple of options.

I have heard that some guys do use the 4th gen fuel tank. I haven't done it but I have seen that it is possible to do here on the forums.

I use the 89 Turbo Trans Am fuel pump, which is the same as the late 90's Vortec 350 engine fuel pumps used in pickup trucks. It goes right into the 3rd gen fuel sender and then I don't have to modify anything. Of course, if you are going to use the engine from the 97 then maybe taking all the fuel lines from it is a good idea. I would probably just modify the lines under hood to fit the LT1 if it was me.

If your 3rd gen fuel lines are shot, how are the fuel lines on the 4th gen parts car?

 

Pick up the truck pump for about $90 at a local store, full braided AN6 lines/fittings will set you back about $300. Diagram with PNs in the additional info thread

 

I haven't been under the parts car yet but considering it sat for four years I can't imagine they are any better. Thanks for the help.

 

Is this the fuel pump I should be looking to get?

That one should work fine, since it is rated for the Turbo Trans Am.

I use AC Delco EP381 (or equivalent, but I prefer AC Delco):
