I received my refurbed sending unit
It looks way better than the one that came out of the 780.
Checked all the hoses for rot and they "looked" ok. After stabbing in the refurbed unit, I hotwired the pump to prime the system and sprung a giant leak. Sigh . . .
The pressure hose that "looked" ok apparently was not ok. It ruptured in 3 . . . THREE . . . places. And of course the hose clamp is completely out of view and can only be accessed by dropping the tank.
Well, jacking up the car on soft dirt was not happening. Out comes the razor to trim away as much as the hose as possible. I took a pair of side cutters and snipped the hose clamp. Success!!
Eh . . . not so fast. I have to get a new clamp on there and tighten it blind. After what seemed like hours of fiddling, I had the new hose and hose clamp on it. Let's try this again . . . .
I hotwired the pump to prime the system and found no leaks.
She's running a bit rough and coughs a bit; not bad for sitting up for 3 years. After idling for about 15mins, it did smooth out a bit, but still has a slight hesitation. Took her for spin around the yard with the rear suspension riding on the bump stops (nivomats are dead). A tune up will probably make her sing. For now, it runs and it drives.
