replacing my fpr today, what is the proper oil to use when replacing the o-rings since its in the fuel system?
x2 just a little dab of motor oil will work fine.I dont know if there is anything specifically for fuel system o-rings. Ive used 30W motor oil to lube up injector o-rings, FPR o-rings and fuel filter o-rings (used just enough to rub the o-rings with). Ive never had any issues.
thats a useful tool youve got right there, i saw it in the store and was tempted to buy it, but i need to be patient, 2 more weeks before i start UTI and get that nice snapon discountYou could have pulled the relay, it is the green one that is next to the EEC relay, and the self test connector. All three are located at the top of the driver's side wheel well. That however in and of itself would not release the fuel pressure that is already built up in the system.
My fuel pressure guage has a hose that one can use to drain off any pressurized fuel, when one connects it to the schraeder valve mentioned above.
