    1991 carburated 4.3 fuel pump output.

    The same fuel pump is on the 5.0 and 5.7 and 7.4 The pump will support twice the HP you can make with the 4.3 Generally mechanical fuel pumps either work, or don't. If it doesn't work, $45 gets you a new Carter fuel pump

    Fiberglassing question

    welcome aboard. I would be looking at 1 layer of CSM, and about 4-5 layers of 1708. then fairing and gel coat. No way I would trust bed liner, especially from harbor freight
