hi all, i have a 1999 seadoo xp 951 that does not read how much fuel is in the tank, is there a bench test i can do to check the sending unit fron the tank and check to see if the gauge is good, also i can't find where there is a fuse that could be blown, i did check the connections, they seemed good...i just wanted to see what was bad before i start replacing parts...i thank you all..
