I have a problem and I hope someone can guide me in the right direction. I put a 04 RETURNLESS type 5.3 into my 01 RETURN type 4.3. I found out the newer fuel pumps are RETURNLESS and have the regulator and filter built into the fuel pump assembly. I would just buy a new returnless pump, but the hole for the newer fuel pump is different than the one that is on my gas tank. Is there some type of aftermarket returnless type fuel pump that I can use. i am just worried about the regulator and the filter being built into the newer style pump and mine is all external on my truck. Anyone have any ideas? Could I just block off the return portion of my current setup and not worry about it? Buy a 5.3 RETURNLESS fuel rail?

BTW I have the RETURNLESS type fuel line that came with this 5.3.

THANKS GUYS!

 

easiest way would be gettin return style fuel rails..that would be the cheepest

 

I agree with Dirt. Personally, I like the return style MUCH better anyway.

 

yep think return is better too..adjustable too with an adjustble fpr
