6an is like 3/8inch line right?
This is what I'm talking about. 1 vs 2
Which is the best way and which order of fpr/filter is best
Thanks
Hoping 300-400hp range turbo k20z1

a 1,000hp engine needs a return. otherwise it wouldn't run at idle and low rpms
both setups are using a return. the way that's pictured is perfectly fine. the traditional fuel in one side and out the other to the regulator may provide a more stable fuel pressure over the entire rpm range.

I have seen a few different fuel set ups for k swaps now and i find the swaps (regardless of n/a or f/i) that run the inlet from the factory fuel filter location on the firewall and the return routed thru a fpr on the LHD drivers side to hold fuel pressure at a more stable pressure than the set ups that dont run a return line.
I have found that the set ups that run a returnless style system get pressure fluctuations at idle, causing slight misfires

How come the 8th gen civic that doesnt have a return needs one after 500/600 hp?
Same reason, runs better, won't lean out at higher RPMs either.
It's really a safety precaution when you're doubling/tripling the factory output. Return line = good.

yea i get that but odz-fab stated a 1000hp engine needs a return was that just an example? because the si's need a return after like 500/600 if im not mistaken
I think some people don't know/understand that the newer civics are 'returnless system" meaning factory the fuelpump is what regulates the fuel pressure inside the tank thus no external return line . referring to a setup with a fpr with oneline only going into the fuel rail as 'returnless' isnot accurate . both setups have a return line coming out the bottom of the fpr.
when boosting a newer civic you need to add an aftermarket fuel pump to meet the fuel delivery needs(wich isn't self regulated in the tank like oem pump) thus you need to add a fpr wich has a return coming out the bottom
hope that helps

I think even more people don't know/understand that cars with returnless fuel systems still use a FPR to regulate pressure. Difference is: the FPR is in the tank, right on top of the pump.
The primary OEM benefits are:
-less plumbing
-lower fuel temps (not circulating through fuel rail)
Why upgrade?
-ability to adjust fuel system pressure
-ability to handle higher bypass volumes
-try running a boost reference line to the OEM FPR...
