    If you have OEM fuel pump might replace it.

    I'm going to throw one in there this weekend. Does it really take that much fuel pressure to make the 48 right?

    Ive run riva 50s , Bosch 48 and 50 with 2rude and no problem getting AFR below 12.
    The bosche 48 have similar AFR as the riva 50 but dont have the issue of the riva have above 65 psi.

    What was yiur AFR with reg at say 60 psi if you recall?
    Was it still in the 12s or leaner?

    Is there a possibility that my 48s are not really 48s?
