Just changed my racor filter and started my motor for an outing tomorrow, and the motor will run a while and quit. I can see the filter canister on the motor start to drain down as the motor runs, it gets to about 3/4 to 5/8 and dies out. If I pump up the primer ball and manually fill the canister on the motor it will start and run for the same amount of time every time until it drains the motor filter housing down and dies.
Anyone got any ideas? I took the racor filter back off and made sure it was full also!! Thanks.
