Hi Bill,

Yes I changed the filter , it was clean , I pulled the tank out on Friday and it was spotless inside, I was hoping to find a rag stuck to the pick up or floating around....

I just went out and bled the filter to see if there was any air and I have noticed that the fuel bulb pump no longer gets firm after a couple of pumps ??

I took the outlet off the filter (hose to engine) and it is pumping good amounts of diesel when squeezed with no air present.

I hooked it back up and took the return off the filter and pumped the bulb but no return came through ??

The bulb doesn't firm up and I have no return ??
