fuel leak
 

my buddy pick up a 95 5speed for $800 the truck runs fine but when you leave it sit for and hour or so it won't start so we sparied it with starting fuild to get it to start but when it is running it runs fine it is losing its prime so where. but my ? is are there common place to check for fuel leaks on these things. the truck runs like a top only has 200000 miles on it.

First off, please dont use starter fluid. Our trucks have glowplugs and those two dont mix. Check the valley for wetness to find the leak.
