Thanks to everyone that responded. Update: Still no fuel. I unhooked the connection at the pump inlet. From that there is a rubber line about two feet long that runs to a hard line. I replaced that rubber line with high pressure fuel hose. The copper line runs all the way to the back of the tank. I unhooked the hard line connection at the tank. I blew air through the entire hard line. No obstructions and no leaks. I blew air into the tank and could hear it bubbling and see vapor coming out the gas cap. With the truck running I could feel very little, if any, suction from the inlet of the pump. I sprayed some gas into the inlet of the pump to prime. It did not take much before it came running back out. I hooked everything back up. I fired up the truck and still no fuel. The guy that rebuilt my pump said the arm on the pump that goes into the block may not be seated right on the cam. I assumed that if the arm gets inserted into the hole in the block and you are able to bolt it up, it must be in the right place. I guess that may not be the case. I might have to remove the pump again? Any suggestions
