1975 CJ-5 not getting fuel
Hey guys. My buddy drove his jeep about 4 weeks ago and it was running like a champ (and has been), but after garaging it for the past month it is now no longer getting fuel. Here is what we have tested:
Previous to driving it 3 months ago we tested the pump and it was puming out fuel fine. It was filling a clear coke bottle in seconds (16 oz). My question is....do fuel pumps break over time or do they just all of a sudden stop working like this during storage. Is there anything else it can be? I was thinking that there may be a crack in the fuel line somewhere, but will that small amount of air getting in the fuel lines prevent the pump from pumping out fuel at all? We currently have the line disconnected BEFORE the fuel filter, so i am 100% sure its not the filter. The end of the line is sitting in a clear coke bottle and not a single solitary drop of fuel is coming out. And yes....the gas tank is full.
Is there anything else I should be checking before jumping to the conclusion that the fuel pump just magically broke while sitting still in a garage for 4 weeks? Is there maintenance that can be done to fuel pumps? can they clog?
