I just completed my filtration system from the plans that are on Frybirds web site. I think this is the basic design that CHenry uses also. I can not get the pump to pick up the oil. I have primed the pump with oil, then I tried water. It will clear the line if I lift the suction line (thats full of oil) high over my head but once I put it back into the oil it stops. The pump I purchased is from Northern Tool and I got the part number from one of the posts here. Any suggestions? Thanks for your help.
