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.
