I have been running my AMT Mercury on a test stand and have been using my retract air pump to prime the fuel pump through the vent line. I just put pressure on the tank and watch all the air bubbles head toward the turbine and shut off the valve before fuel starts entering the engine. This works fine but now that i have the engine mounted it is hard to see the fuel line going into the enigine, also the closest spot for the shut off valve is about 14 inches from the engine. Just wondering how you guys take care of the air bubbles in the lines without filling the engine with fuel. Everytime I try to start it without priming I get a "rpm low error". I am trying to aviod a BIG flame out the back due to a wet start.

Thanks for your ideas
Bill
