Fuel Pump wont prime ???

As I noted earlier, if your fuel tank is a little crusty, be warned that the U type non returns are less forgiving.

I have a U type on the fordson Major, it was a PITA until I flushed the tank, similarly father had similar issues with the RP running one of Jamies new ones. He went back to the T type top on the bottom of the new U type.
