Hey!  First post on the forums been on the facebook group for a bit.

I have a 78 cougar bubble deck with a mild 468 n/a.

Last year I had problems with the boat everyonce in a while running out of fuel under acceleration,  it would shut down.  You would re-prime the electric pump (carter ~70gph rotary vane) and you would be off to the races again, it did feel like it was running out of fuel up top.  Only had the boat out twice for short periods decided to deal with it over the winter.

So I noticed I had sucked one tank almost dry' the other almost full, so Re-ran the fuel lines so they were equal length hoping that may even it out a bit (Glenn has corrected me on this).

So today I go and try and start the boat to head out.   Fuel pump wont prime.

Take it out bench test it.  It works great. 

Fuel to the pump.  No fuel out of the pump.  I can blow in the tank with an air hose and push the fuel up to the carb but even than the pump doesnt want to take over.


I am thinking that I dont have enough volume of fuel coming at the pump for it to pump efficiantly, as rotary vane pumps are not the best at scavanging fuel?

Soo..  How should I approach solving this?

I am thinking going back to a mechanical pump would probably be easyst as they are great at sucking fuel out of tanks..
