Was wondering if anyone had some thoughts on why my friends 95 2500 was losing the fuel prime when the truck sits overnight. In order to start the vehicle he says he says he must pump the lift pump a dozen or so times then it fires right up. someone told him it was the washer in the fuel filter, but he had that looked at and it seems to still lose prime when left overnight. As a first gen. owner with the old style fuel pump arrangement I wasn't much for advice-any tips on where to start looking would be grteatly appreciated. Thanks.
