Fixed the fuel leak
I posted back a month or so ago about my fuel leak when the truck was full and parked at an angle. I finally got a chance to drop the tank, and the leak was coming from the sending unit O-ring. The old one was hard as a rock. I don't see how it could have ever sealed.
It must be a halfway common problem because the new O-ring is made of a completely different material. It's very pliable and made of some kind of green material. The old one was black.
I filled her up to the brim and parked it at about a 20 degree angle overnight and didn't lose a drop of fuel. I'm so glad to have this fixed. Losing 1/4 tank overnight can get kind of expensive. LOL
