    Fuel pressure drop

    I went out today with a buddy of mines and his RXP is having a drop on the fuel pressure.He has a gauge installed and when he comes out of the hole the ski will rev up normal for about a second and the it will lose power,the fuel gauge would drop completely and a second later it would continue to run fine for the rest of the quarter mile. What could be causing this to happend? Oh by the way he just installed 42 lbs injectors.

    Is it possible that the pickup is getting air or even collapsing?

    My fuel pump had a cracked nipple from day one. It broke when I hit a sideway`s wave.The ski would run but had no power.
    The pump would move around. Fixed it and have had no problems.
    This pump module has two screens, one on the outside under the module and one on the inside. If the pump has come loose from the base of the module it could possibly cause your problem.
