    so my cousin brought me a bosch inline fpr.....to adj my fuel press because the chip is putting my fuel psi @60....


    anyway.....can i put the FPR on the fuel return line and leave the stock FPR on the rail....????????

    well thats what i did and before i got to adj the psi the engine tuned off..( it jumped to about 90)..and would not start so i took out the plugs and cranked the engine to expel the extra fuel....but it still wont start...

    fuck i hope i did not fuck it up....lol

    any comments are welcome....

    why are you listening to your cousin he is a dsm head.
    dont put a fpr on your return line
    i know some people that did do a switch for thier fuel pump and they didnt use relay and didnt have any problems

    i would say it goes inbetween your fuel filter and fuel rail. but I am just taking a wild guess at that not sure which one you have.

    try the switch and see if that helps with the pump

    What? NO!!! A FPR goes between the fuel rail and the fuel return line...NOT between the filter and the rail!!!!!

    yeah what he said. LOOK at where the stock regulator is. At the end of the rail with a return line coming off of it.

    why in the hell would you try and fix a hack with another hack...

    your chip obviously sucks ass...
    if you're gonna run a fpr you should at least get the right one...

    get rid of the chip, or get it fixed...

    hack on top of hack is inviting more problems...

    you can put a switch to your fuel pump with no relay but i would avoid that at all costs... you will forget to turn it off sooner or later and kill your battery and possibly fry your pump...
