I'd like to make my '03 LQ4 into a returnless fuel setup for a swap. Can i put the new returnless fuel rails on that older intake? Or what would it take to make my setup returnless?

i did a quick search but didn't see anything on this..

Anybody know???

not sure about the newer tuck rails but the LS1 rails have a low crossover that wont work

Yea i had read that the car fuel rails wouldn't work... i would be awesome if i could just bolt on a new (i think '04 and up) stainless returnless fuel rail setup to my old truck intake... i don't want to swith to a newer intake because i'm running cable drive throttle body.

The mid 2004 and 2005 ups returnless rails will work with the earlier intakes. The flex fuel motors had the stainless rails as well.

You could just buy the whole later returnless intake as most times they are $50 bucks complete lol And just unbolt and bolt in the new one.

So i need a non-flex fuel returnless rail setup? Is that correct? Should bolt right up? are my injectors the same or are the connections different?

The flex fuel stainless returnless rail wil swap over to your current intake and injectors. You should be able to get one cheap. I've bought intake/rails for $35.
