  • Sorry, need fuel pump not injectors.

    I traced my problem back to a fuel pump that was not holding preasure. I bought the Granatelli f-body intank fuel pump(could not find a Walbro, even though i think walbro supplies everyone a pump and then they put their name on it like Holley). Anyone hear any good or bad things about the Granatelli pump, i think it is a walbro.

    I've been running the Accel injectors for a year now. No problems.

    James (12sec) ran bigger Accel injectors and had problems.

    Magnus ran Accels too.

    On a local f-body board I'm on, the rumor is that Accels are prone to lock on top end, and that SVO injectors are preferred. I haven't had any locking problems that I know of.

    If you're running a dry kit, the stock size injectors should be ok to 100hp, maybe 120hp. Beyond that, you could need bigger injectors (or convert to a wet kit). Best way to tell is to monitor the pulse widths of the injectors.

      Thanks for the help John_D, I think I will buy the Accel injectors. I am pretty sure I need the 22lb injectors, which are the factory size. If that is not right, could you please tell me, and if it is not a pain, could you give me the exact part number for the replacement injectors you used for accel, Thanks.

        The Accel catalog:
        http://www.mrgasket.com/accelpdf/ACCELfuelinjection.pdf

        They list a 19 as stock, but I don't think that would be right.

        150622 would be the 6 pk of the 22lb.

        I put the 24's in mine. Had to adjust with a maft for them though...

          accel 24 lber's and nos kit 5175 with dry 120 shot destroyed my engine in 1 month due to tuning

          Stay with a stock injector..... that is my personal feeling.

          I run stock ones now

                James I just wonder if you have any concrete proof that the injectors caused the problem with your motor. I don't think so but, who knows... [img]smile.gif[/img]

                    Wasn't over revved.... tuning issue.

                    It started as soon as I installed the bigger injectors.

                    Stock works for me.
