    Riva rrfpr

    Hi,

    noob questions ... I have removed the fuel pump from the tank, My noob question is ... Electric wire in gaz ... This is not dangerous? Are all those electric wire soaking in gaz? In the instruction, we need to attach the ground wire but will this wire soak in gaz ...

    This is probably normal but, not dangerous?

    Thanks

    Completely safe and normal all in tank fuel pumps are like this. Cars, trucks, you name it.

    Is there any safety, let's say there's a short circuit inside the tank ... Is it going to explode or?

    Anyway, that was the noob question of the day But I could not found the answer ... I have a real question what's the factory setting for the Riva FPR? is it somewhere around 50 psi or ??? They say would have to start the engine to adjust the right fuel pressure ... But what if the factory settings is too low or too high? is it going to cause issue?


    Thank for your time

    Our regulators don't have a "factory setting". You are required to set them to the prescribed specification for the upgrades you're running. EG - Our Stage 2 Kit requires 65psi static pressure and the regulator configured for NON-rising rate (no vacuum line).

    Didn't know that liquid gas / high quantity of gas vapor is not flammable because there's no oxygen to make the perfect mixture ...

    Thanks for the info RIVA CREW ... I was asking because when I start for the first time after the RRFPR installation ... I was wondering what if the regulator is not giving enough pressure, the engine would not start? what if it's giving too much pressure?

    Before I start the engine, do I need to make a rough adjustement or I just install the regulator and crank the engine and quickly adjust to 58psi ...


    Thanks.

    Thanks.
    Wake the machine, adjust if necessary to around 58psi <--- good starting point (CHECK FOR LEAKS!), then start and verify psi(shouldn't drop that much) You will need to adjust after that for AFRs. Jonatan "usually" makes his tune for a 58psi static pressure.

    Where you guys hook the FPR on a 2012 RXT ??? I have checked my ski and it's not even near of what's in Riva instruction ... 1st, no fuel vent on the tank ... And, the place they bolt the Regulator, it not close to whats on the intructions ...

    I think I will need some imagination...

    The instructions are from older models. Some have made brackets and mounted it to the motor. I mounted mine were you are thinking.

    Also on the newer ski's the gas cap has a built in vent,

    The stock fuel pressure should measure around 58lbs, but we have found that some are way off. Mine was around 48.
    So if you installing it on a stock machine set it at 58lbs.
    But what mods do you have? Most ECUs like 58lbs, but Rivas Stage II it is 65.
