i have a 2004 gmc sierra with a 5.3 lm7 with a return-less fuel system. im currently running stock fuel rails, siemens deka 80lb injectors , walbro 400 fuel pump with the hotwire kit. im wanting to put in a boost controlled fuel pressure regulator but im not sure what one to go with. i been looking at the areomotive universal ones?

ive also been trying to cram info on all this but from what i gather is i will have to convert the system to a return style system and may also have to get some new fuel rails? if thats the case i think i got the rails picked out and i know if i need to convert it i can use a -6 line. but if i have to do this im not quite sure how to hook it up and run it. also dont know what all fittings id need and how long of hose? i appreciate the help guys.

 

im going to try ad have it tuned for 8psi for now until i can afford to do a returnless set up so far ive come up with this.

do you by chance have any pictures on how you modded the top of the bucket and how you ran the return line? i know i wont need the bulkhead and stuff inside the bucket because im running the single. also what regulator did you end up going with?

 

I drilled a hole in the top for the bulkhead and wires. Thats it.

Return line follows the feed line that followed the factory fuel line path.

Aeromotive 13101 I think...

 

The regulator you posted has -8an in/out. Look for ones with a -6in/out. Or I could sell you mine since it's going to be awhile until I get a new motor for mine

 

What about building a quality feed line and using the stock feed line as a return line?

 

Done it that way plenty of times, works fine.

 

Would it be better to just do that use the feed as a return?

 

Here is mine.
