    New problemo
    « on: April 01, 2017 - 08:38:04 PM »
    Coming of line today, getting some studdering in acceleration.
    Fuel pressure dropping from 5.5 psi to 4 psi.
    Got home, and rubber fuel line nearest radiator was 190 degrees.
    Must be getting vapor lock?  Will move and insulate fuel line.

    I changed mine to steel braided with the DEI sleeving and that seemed to help.

    Will keep in mind. Considering a major reroute at this time.

    ok, moved line up against, and under, distributor, and put pipe insulation over it.
    So its 6 inches further away from radiator heat.
    Having a fuel gauge in the car was very helpful in determining why
    engine seemed to be losing power.
