looses prime when parked up hill overnight. replaced return gaskets on return manifold.the line  from the filter to inj pump replaced, they checked for bubbles in a clear line between filter and inj pump by the shop who did the work none found.said it started right up when parked up hill at the shop.

but its not fixed yet still has to be primed with the lift pump. If you crimp the inlet line at the filter when parking it, it starts right up next day could be the fuel pressure gauge line,but then there would be bubbles in the line,maybe. Taking it back to the shop tommorow that did some of the work. will let you know.

Not sure what "manifold" you are talking about with a return. There is one on the back of the cylinder head and it ties into a tee about a foot below that. If air is getting into the return line on the back of the head and/or the tee below, it would not show up in the fuel supply, ie the clear hose you used. Both are after the supply side of things. They allow air in and the fuel drains back to the tank. Crimping the line cuts off the route for the fuel to go back to the tank.
