Hi,

I have just installed a new secondary rail, 1600cc secondaries, had the stock primaries cleaned and flow tested, SARF FPR, braided lines and Walbro pump fitted.

I want to know if I have sufficiently checked the system for leaks. So far I have pressurised the system to about 38psi (no vac line), by KOKOing. There have been no leaks.

Also, after switching off, how long should it take for the pressure to drop, and by how much? I have read that if the O ring where the fuel pump is connected is not seated correctly, pressure is lost by fuel leaking back into the tank.

Thanks
