"weak" fuel pump
My '72 petrol SWB came with an electric fuel pump in addition to the mechanical one. Although it can run with only the mechanical one it eventually starves for gas and dies w/o the electric one supplementing it. As the whole fuel system is new I assumed that the lobe inside the engine was worn and the pump wasn't being fully articulated because of that. However I recently found an old Rovers North receipt in one of the manuals so I wrote the previous owner a letter (I bought the vehicle off e-bay from someone who just flipped cars). He said he installed the electric pump because after the truck sat for a while it would need to be primed and he didn't want to climb under the truck. Suprisingly my theory of a worn lobe is unlikely as the truck only has 20,000 on it, I had assumed that it has turned over! Before I put on a new fuel pump (wife is starting to get tired of me spending $ on my truck) could it be that the newly installed one just be defective as evidenced by the need for priming? If I do replace it has anyone used the new style one offered by our hosts or should I go with the pro-line replacemnt with the sediment bowl?
thanks and sorry for the wordy post
