Modified fuel lines

I know the RR systems are a very good system, but instead of putting in return lines for a traditional RR, has anyone ran supply lines to all four corners instead.
That way you still would remove the chance of starvation of the #1 and #8 injectors. Then use a fuel lab PR to adjust.

Now technically this would not be a RR system, it would still be more of a pressure relief system.

if alone, just reroute the d/s line to the rear port, you'd see a noticable difference in "cackle" noise, to the extent its not even there...

Id say just do an OBS style E-fuel system. Fuel splits from the pump goes into the back of each head and comes out the front and goes into a FPR then back to the tank. That removes the fuel bowl too really clearing up the valley

Edit: only deletes the fuel bowl if you install inline filters(obviously)

Correct, thats why i said, plumb d/s line to rear port. Ever hear an OBS "cackle"/tapping sound, from the a/an injector?

Idk i dont think ive even heard this "cackle" everyone talks about. Even on my SD and it has the stock fuel system. Is it an obvious sound?

Well I emailed Dave at Swamps and he gave me some good info. What the idea can essentially do is create a more budget minded way to supply fuel that does work instead of a higher priced full blown RR. I.E. you can get the stronger spring and save yourself the $150 for a Fuellab PR. Not saying any way shape or form that's its better, just different and that can fix the end of the line starvation issue. Here is Dave's reply.

yes, I have a customer running our 400/400s, twin turbos, etc...that did exactly what you are describing/proposing.

while I can appreciate the theory behind this...we don't believe that it is any better/different than a conventional fuel return system...

ie...all of our (relatively) high power trucks, as well as our engine dyno is setup to run a conventional pump>>heads>>return...and have no problems with injector performance at well over 1000hp.

I'm not saying 'don't be different'...I am just sharing with you, our experience.

take care~

Ramm..i wonder if the "cackle" is more noticable with L99/E00 with all AD injectors. My buddy's 01 has the AE/LL injector in #8, and no "cackle at all or very minuute. While im on D2, my injector bangs away like a "little person" is in there with a ball-ping hammer.
