OK, first the story......
I inherited this 1992 F250 (currently 79k original miles, got it with 71k) from my grandpa when he passed away. It had sat for 2 years prior. I spun the filter off and siphoned the tanks. Poured Power Service in the new filter housing and put fresh diesel in the tanks. It ran fine for a few thousand miles. Now when I was driving the fuel filter light would come on and go off every once in awhile. Then while running on the rear tank one day it came on and stayed on until the truck died. I got it restarted switched tanks and drove it home. The next day it wont run on either tank. I spin on a new filter. Still no go. Check fuel pressure, there is none. Slap on a new Airtex fuel pump and bleed the air out. It runs home on the front tank fine, switch to the rear tank and within a couple miles the filter light will come on and the truck will die. I'm thinking the tank must be bad. I purchase a new rear tank as well as a new rear tank. I drop the rear tank. It was full of rust and what looked to be red algae. I replace it along with a new sending unit. I'm happy with my work and the truck will idle and run with the new tank. I drive down the road for awhile switching tanks every once in awhile. Then after awhile the filter light comes on and once again the damn truck is dead in the water. It will only run on the front tank. I was planning to replace the front tank also but now I'm afraid to because its the only thing keeping the truck running but im sure its not in much better shape then the rear was.
I'm at my wits end. I don't want to let the truck go because it was my grandpa's and its in great shape. Whats the next step? I hate to just keep pouring money into it.
Thanks for any help.
