Need help with fmu fuel line please
Hey guys,
I installed a basic bolt on turbo kit onto my b20 integra.
I'm running a 12:1 blox fmu at the moment. I do have a chipped ecu that I'll get tuned. But this is just a temporary solution and I don't beat the car long or hold it under boost for very long. I'm only running 5psi at the moment.
My question is I keep running into an issue with the fuel line that goes from my fpr to my fmu.
I installed a line I had that came with my adjustable fpr (not installed) which had a stamp for 3.4 bar. This started to weaken after a few drives and I noticed by some backfiring and fuel smell. So this was clearly leaking pressure.
I went to the auto parts store and picked up a line rated for 6.9bar (100psi or so I think)
And just now it started doing it again, the car starts running super rich and I can see the line being over flexed and such.
Stock fuel pressure is 35psi I believe.
I'm trying to do the math in my head and I can't seem to wrap my head around the calculation to determine the pressure it's holding when under 5psi.
In any event. What do I do about sourcing a line with enough pressure to hold this?
It'll be another month or so before I source my injectors and fuel pump and have the funds to throw it on a dyno. I just get worried about it running so damn rich. Thanks for the help guys. I searched and couldn't find much

I didn't. I have an adj fpr with one on it but I haven't installed it, I figured out it was definitely sticking closed. I pulled it apart, and it seems to be not happening as much except for a long 4th gear pull, when I shut the car off, and turn it back on it fixes it every time. But I just picked up some 450's and I'm getting a safc this week and I'm just gonna do the hack
