I'm swapping in a 5.3 into an 81 Malibu.. previously I read that I could just used a vette filter/regulator and run a single feed line.. easy enough..

However, some 5.3s had a return line. Do I just cap the factory return and run a vette regulator or do I run a normal feul filter, and run an extra return line?

Thanks

Or you could put an ls1 intake with returnless rail and the vette filter/reg. It'll look much cleaner, and won't need the extra line run for return from the front.

If your gonna keep the 5.3 intake, you dont need the vette filter. Just get a 5.3 filter and run the return back to the tank.

Can do it a number of ways, but I wouldn't recommend just blocking off the return on return-style rails. Some truck rails are non return style and would work better with the Vette filter/ regulator if you are aiming to just use one fuel line. PM me if you want some of those rails, I believe I have some.

Which year vette/fbody had a returnless rail and would I need to swap injectors or can I retain my truck injectors?

My setup was off a 98 T/A. Not sure if you can still use the truck inj. but im sure you can get the ls1 intake/rails/inj. for cheap.

Ive read that I also have to relocate tensioner and change water pumps to clear intake

Some people rotate or bend the filler neck on the water pump so it clears the intake, and are able to use their truck acc.

I got my vette regulator/filter at oreilly auto parts, i think i asked for a 00-03 vette one.
