running ritcher?

[TRD_ZERO]

It's been awhile since I've been on here do to lack of issues with my car. After driving it the other day I noticed a fuel smell inside the cabin which haven't been there. Found the fuel reg to be leaking out of the return fitting. So I cleaned it it up and sealed it up again. It doesn't leak now but I'm still getting a fuel smell in the cabin sometimes at idle. I've also noticed the exhaust fumes smell rich And its popping abit more than usual. It's a ae111 blacktop turbo running a g4 with 550 injectors. What should the reg be set up to? When I prime the pump it goes to 3 bar on idle it sits at 2.5 bar. what should I check next? Thanks

The only way to do this properly is get a wideband and check your idle's O2.
You can always try trimming fuel at idle. FWIW the usual pressure is 38-42ish PSI for idle pressure, when you prime the FPR will probably bump the pressure since it's seeing atmosphere pressure instead of idling's vacuum pressure.
