HELP! Fuel issues crushing primer bulb under vacuum

[Shrek]

Yep, everything is 3/8. I'm setting up a filtering rig this afternoon. I figure that I will jack up the front of the boat about 47 feet in the air and loop the fuel through an electric pump through a couple of filters/water separators and back into the tank through the vent. I'm going to run that all week and then we will see what happens.
