I have a question for you guys:
A month or so back I saw a post over on the other forum where one of the guys had a lot of problems priming his fule filter after replacement. He sealed off his fuel filler neck and added compressed air (low volume & pressure) to force air into the system & in effect, prime his filter for him. Here is a copy from his post:
--------------------------------------------------------------------------
I changed my fuel filter again. Done it before twice no problems. This time I pumped the primer literally thousands of times. I had a blue bruise on my palm yet no fuel. The air bleed screw (new stainless) was open as well as the gas cap off. I took the filter off. All seals good. I pumped the primer with the filter off. No fuel.
Towing to a dealer was not going to be an option. I was in my driveway. Maybe I should of turned the truck around. The nose would have been more downhill.
Anyways I got to thinking. The fuel pump is upline from the filter and pulls a vacuum. The hand primer must pull a vacuum too. What if I could pressurize the gas tank a little and push the fuel to the filter?
I looked at the filler opening and tried to figure out how I could make a seal and put compressed air in. I ran into the house and started digging through the dog's toy basket. What are you doing my wife asked. Ah ha. a tennis ball. I ran back outside, cut it in half and turned one half in side out. I punched a small hole though it. I mounted the ball inflating needle on the end of the compressor hose and pushed it through the hole. I then pushed the rubber side of the ball into the filler neck. I pushed it tight with my finger tips and squeezed the lever gently. The tank filled with air and belched. I continued this for a minute or two. When I went around to the filter assembly, It was covered and dripping sweet, beautiful diesel. I closed the bleeder screw and it started right up. Ya hoo.

Has anyone hear of this? Can it do any damage? Sure seems like it would make things easier if you could force fuel into the filter and out the bleed off valve to prime it. I know you would HAVE to use LOW PRESSURE / VOLUME . . . But what do you think. Give me some feed back. Will it hurt the system?
Thanx,
