    rude rrfpr

    I was wondering on the rude rrfpr, if it's normal for the pressure to slowly drop off after shutting the ski off? thanks

    that's interesting, on my ski with a rude rrfpr, if I have it set to 55 base, it will drop to around 20 lb after around 10 seconds of shutting off. I just set up another ski with a accufab rrfpr set at 48 base and after half an hr, it drops to around 42 lbs and after another hr, it dropped to 33. I guess different regulators work differently.

    NO, pressure drops off because you are removing the factory in line one way valve that is built into the factory fuel regulator once you install a FPR tank adapter

    meeper, they are both set up with walbro pumps and both using the rude adapter. why would one lose over 30 lbs in under 30 seconds and the other lose 15 lbs after an hour and a half.
    the check valves are actually built in the fuel pumps, not the factory regulator.
    my ski with the rude rrfpr is not here but the next time I get to it, I will try pinching the return line and seeing if the pressure drops.

    the check valve is in the factory regulator from what i have been told by so many ppl.

    diff in pressure drop could be a sticking reg
