Glad to see the problem is resolved. Who'd thunk about that!!.  I will certainly save this tidbit of information.  We try to never let our fuel level get below 1/4 and try to always top off the tank when returning from a trip. A full tank has less space for condesation to form=less chance of algae problems. Jack

Jeremy,

To add to what Lee said, the 4104 fuel pump is a mechanical suction pump mounted at the engine so the complete supply line up to the pump is under suction, only from the pump on is it a pressure system. This is the reason it is hell if you have a leak before the pump!! I think the pump pressure is around 35 psi but don't hold me to that number.

Jeremy,

Look at some of the Bedford engines. Those are pretty much a DD engine, just rebadged. That is NOT to say that they are a 53, 71 or 92 series for you purists. Bedford was bought out by DD a longtime ago.

Another way to look at it is to look at a Jag XK injection pump.... it was mechanical and didn't self prime either.
