Evinrude 2 hose fuel tank

[benji41]

Have a question—should this fuel tank hold pressure when not attached to motor and should you hear the pressure release when fill cap is opened slowly?
Thanks trying to figure out why no fuel to motor.

Yes to both questions.

The gaskets for the tank are available, as well as the o-rings for the fittings.

Is there a check valve in the pickup that is stuck open or closed ?

So you are saying if you have the tank hooked up to the motor, and you prime the button it will not fill the carb bowl?

Or….it will not pressurize while running to keep fuel flow flowing?

Chris-p I had it running a very short time then quit (with fuel in carb bowl) now will not start. Very good spark and rebuilt carb and plugs not very wet just like a light mist of fuel on them.
With tank disconnect and I pump the prime button then open cap no pressure.

That button does not pressurize the tank.. it only sends fuel to the carb. The motor when running sends pressure to the tank

Time to disassemble tank and clean. Replace diaphragm and top gasket. Inspect lines for cracks. Make sure valve in pick up tube is free and functioning. See above, primer pump does not pump air

[Mumbles]

As stated, the primer button on the tank primes the carb. If the tank is nearly empty, you may have to keep on pumping the button a bit to keep the motor running until it can build up enough pressure in the tank for the fuel to flow on its own.
