Add a lift pump. Run it for a while that way. Remove the lift pump and see if it is cured.

thanks for the reply...any recommendations on a lift pump?

Anything putting out a fairly high flow rate which you can draw fuel through when not operating will work. There are quite a few Facet Posi-Flow pumps which are suitable. Keep the pressure below 10 PSI or you may end up with leaks at the pump shaft.

huh, cause on mine they will no longer prime theirselves, so i prime in line; pull off fuel filter, and manually prime, if needed it keeps/gets me going.

If everything is moving right there should be NO vacuum at the front of the pump.
Got clear fuel lines?
