Hey everyone.  Left the desert scene and picked up my first jet boat a couple months ago. 78 Bahner....and of course it wont start after sitting for a few weeks.  It does not seem to be getting fuel. Brand new fuel pump did not cure the problem.

 The fuel filter between the pump and regulator does not fill at all when the pump is turned on. Pulled the seperator filter and it only had a couple ounces of fuel in it.
The motor fires up with starter fluid.

Fuel tank pick ups? Hard to believe they would both go south at the same time. Air in the system somehow? Any help appreciated. Glad to be a boat owner still! Glad to be a part of the forum.

disassemble your system.  run it without a filter and use just a gas can connected to the pump.  it should fire up and suck fuel out of the can.  then put your water seperator/filter between fuel pump and can.  does it run?  then ditch the can and run it to one tank.  does it run? 

just keep trying but start with it simple and go from there.

First of all welcome to Socaljetboats.com (don't forget to check out the new videos)  :thumbup:

Do you run a mechanical pump or electric pump?

Either way try priming the fuel line to the pump, or take the line off the carb and fill it full of fuel. If the pump is mechanical get yourself a cup and fill it full of gas. Get the boat to run and use the fuel in the cup to keep it running. This will pump the mechanical pump long enough to get fuel. Then you should be golden.

If however, you are running a electric pump. There should be a "T" between the tanks, and may even have a shut off. Check that "T". The lines could be rotten, or even off or the "T" could be closed. When I had dual tanks I had an air leak in one line and the boat wouldn't draw from either tank because the fuel would reach the "T" and then get full of air. Almost like poking a hole in the side of your straw.

Give that a try and post back. Pictures always help

Does your fuel tank have check valves in it or clogged vent lines try those after you inspect ur lines for cracks   Do some back tracking did you do anything else  before the problem existed

Definitely run it out of a gas can maybe it just needs to be primed 1st my dads elimantor with a 460. Would never start back up once he'd run it empty. Might be a ford fuel pump thing

Yeah, going to run the pump out of a gas can, hopefully prime the system. nof the fuel pickup hoses is cracked near the connection, going to replace that. Going to figure this out. Thanks!

I generally drain my tank on off season, clear lines and remove carb running mystery oil through it all....Only takes a few seconds to get the new fuel back to carb and I have a mech pump (BBF).  You could have a loose fuel fitting which might be enough to suck air and not leak fuel.
