hey guys, well i was working on my dads boat today and last trip out he lost all fuel pressure, we thought it was the electric fuel tank selector switch, changed that to a manual. then got fuel but way to much psi for the carb, got new fuel pump but not getting fuel to carb if i hook carb up directly and by pass the water fuel separator set up i have fuel, my question is, is the pump too weak to pull through the separator or is something blocking it or am i just completely wrong!!!!!! im ok with admitting that, please help us get this thing runnin. thanks guys really appreciate it.

is it an electric or mech fuel pump? electric fuel pumps are NOT suckers, they're pushers.

Just because it's been that way for 20 years doesn't mean it's right. An electric fuel pump needs to be gravity fed to the pump (as much as possible), and then it will push the fuel through whatever is in line.
It sound like you might have an obstruction at or near your separator. Remove each item one at a time until it runs, then start putting them back one at a time until you have confirmed the cause (hoses, separator, fittings).

My dad is going to be working on it today. I will let him Know, hopefully he will have some patience :banghead: with a good night sleep, I know it has to be something simple, just haven't figured it out yet! thanks and will keep you posted.

This may not be the problem, but is worth checking. Sometimes the "draw straw" inside the fuel tank will disconnect from the 90* bend at the top of the tank where you connect the rubber hose. Many of the old fuel tank pickups were glued in place. Good luck.

Thanks guys for all the help and ideas to look at its now fixed the problem was a fitting that was cross threaded so the pump was suckin air after that was fixed she fired right up and idles with no problem and sounds like she should

Just a little note, thanks to all you guys with the tips, Boat is fixed and running like a champ. It was sucking up air from the pump to the fuel separator, the threads were done and the seal was not tight. Was happy to call my Dad and Mom, only to have my Mom hold the phone out and it was sounding great!!! Thanks again, to all.
