[Rhodes22-list] 3 gallon portable gas tank question

[The Rhodes 22 Email List]

I agree, your vent is a problem if it won't open.  And pressure would help
push gas towards the tank.  The primer bulb's one way valves don't work
very well with air in them, which is what you now have at this point.  Try
getting the tank up higher than the bulb.  You might also need to loosen
the connection at the motor to allow the air out until the bulb area has
fuel in it.  Double check the connection from hose to tank to make sure air
isn't allowed in at that point. Until the bulb pumps up firm, you still
have some air in the line.

Those bulbs are often located close to the OB motor for convenience but I
relocated mine closer to the tank after experiencing similar trouble to
what you are having.
