Losing fuel pressure
My motor has cut off on me the last two times I have taken it out. It will slowly die like it is not getting any full. I thought it was water in the fuel water seperator and so I dumped it. It helped some but the last time it happened I felt the bulb and it was empty. I got it running again and it ran to the dock with no problems.
Are there any tests to see if your fuel pump going bad? Any help from you "V20 Jedi Masters" would be appreciated very much!

Same thing happened to me and it was an obstruction on the pickup in the fuel tank. Apparently some debris got up around a sock filter on the pickup and blocked the fuel. I didn't know what it was at first so I replaced my fuel water sep filter and it fixed it for a day or two then happened again. All I did to fix it was un hook the hose on the water sep that runs to the fuel tank and blow in it. I could feel it "break loose" and hooked back up and no problems.
Good luck! I hope its something simple. As for your original question, I don't know how to tell if a fuel pump is bad. I'm sure the outboard techs will be here shortly! Hold tight or try what I said. Blue

What type of tank(s) do you have?
Does the possibility exist the vent is closed or blocked? Hell add to your signature the year boat, motor and horsepower (if you got a Gayliner, we'll refer you to CTT). If it's the fuel pump you can prime it and keep pumping to make the motor run. Sounds more like a blocked line like Blue said. If you go to the trouble to unscrew the filter, replace it. Most tanks have a filter screen at the fuel fitting (exit) in the tank, one of mine was 95% clogged with debris.

Ah yes, good advice Tsub - forgot to mention the squeezing the ball test!
If it is blockage you will not be about to prime the ball at all. Mine "sucked in" or collapsed. Good luck Fish!
