If you are getting air into the fuel system the truck will not run properly and the injectors will be starved for fuel which is going to cause the injectors to prematurely fail.

You may have a leak in you fuel system somewhere between the HFCM and the fuel tank. I would definitely have it looked at before it cause major problems to the injectors.

garcherd is starting off with a positive reputation.
The Ford Motorcraft fuel additive is good stuff. One bottle treats 125 gal of fuel. Make sure to use the one for 6.0 PSD as they make one for the 7.3 and it's different. If you have never used it before, put a whole bottle in (1 quart) when you fuel up and get on the highway and drive it like you stole it. That additive will keep the EGR from coking up and sticking. Sells for about $6.50 a bottle, that's cheaper than any mechanic.
