I've been searching around and cant seem to find the answer.

Are the feed/return lines on my crossfire set up sufficient for an LS swap, or should upgrade those? Also what are my options on fuel pressure regulating? Is it better/easier/cheaper to ditch the stock lines and do the corvette filter and use all new rubber lines???

On the subject of the vette filter(part 33737 right?)...is it best to use a delco, or does the wix work just as well? I looked on the NAPA website and they dont list it, so I guess getting it local is out. I guess I'll just order from rockauto or an ebay store.

 

The stock lines will support ~500 HP with a proper pump.

I'm using the Wix 33737 filter in the LS1/4L60E car. O'Reilly stocks it (or will be able to get it quickly - I entered "85305" for the zip in their website, said it's available in store). I adapted it into factory fuel lines.

For the LS1/T56 car, I used a 4th gen LS1 tank, and fabricated all new lines for it. In that case, I just used a 3rd gen EFI fuel filter.

 

Cool, thanks for the response and research!! I looked it up also and for some reason didnt come up as avail?! Oh well...I'll go in and see whats going on.
