Fuel loss on a 460 ford with a carb and a electronic fuel pump?

Question

I own a 1990 ford motorhome which is powered by a 460 / 5.7 gas motor which is a carb motor with a electronic fuel pump. Well i was driving for about 80 miles and then when i came off the exit ramp my motorhome shut off because of lack of fuel.. I checked everything and it seemed ok but i took the air cleaner off and found that i still was not getting any fuel while trying to start. Well i sat there for about 15 mins till it started back up and another time that it happened it took 2 hrs to get started and then i got fuel and then it ran great like it always does it runs like nothing ever happened.. I replaced my fuel filters and fuel cap so they are new. Is my Fuel pump starting to fail? did it vapor lock becuase it was hot out? Is a relay shutting me down? Please help !!

Answer 1

more than likely there is rust or something in your fuel tank that is plugging the fuel pickup.

Answer 2

It could be vapor locking or the relay is getting hot . When my truck did that it was the relay,so  that,s why i'm telling you to check the relay.When i was growing up they put a wooded close pin on the fuel line to help with it from vapor locking.
