Be prepared for the worst, but hope for the best.

You were right,I checked my fuel line where it screws into my new gas tank. It was cross threaded !  After fixing that I put an fe pump I had on , the filter is now full. I’ve got 3 extra ac duel action pumps. I’m going to send one to Arthur Gould to be rebuilt.

This is where diagnostics kick in. If the pressure test is showing low, you don't condemn the pump right off. You check the condition of the entire system looking for any defect (as you found), collapsed hoses (be sure ethanol rated, etc.

You put a vacuum pump on the disconnected line to the pump and see if there is sufficient draw. If not, you have a defect/blockage.

You cannot use a fuel filter before a mechanical pump (unless an electric is before it) as you will most likely experience vapor lock/blend separation. A mechanical pump is designed to pull and an electric to push.

Is the FE pump dual action?
