If you don't already know it the PD can blow out in the primary fuel rail causing big problems. I blew my engine at the track last week when the PD decided to fail causing a sudden drop in fuel pressure and instant detonation on the front rotor. Last month a friend blew his engine at the same track, so yesterday when we were installing his new engine we did the routine fuel system leak test and low and behold another PD fuel fountain. Check your PD regularly, if it goes undetected on the street your engine will catch fire, on the track your engine will blow. Just one more thing to add to your routine check list.



BTW we eliminated the PD from the car yesterday by tapping the fuel rail and installing a brass hose barb fitting. $1 vs $130 for new PD.

i'm running a SX FPR... built in PD https://www.nopistons.com/forums/pub...#>/biggrin.png

I am running the SX also, but didn't think there was a need to eliminated the OEM PD. I will be installing my new engine this weekend, so you know that POS PD will be eliminated.

that's the reason I went all AN fittings....eliminate anything stock that may fail.

yup my whole fuel system is ss braided line and an fittings. cost alot of money but cheaper than buying a new car because it burned down!
