Fuel sending unit problem? 95 6.5 diesel Tahoe
We just installed a new sending unit in the Tahoe. Added 5 gallons of fuel. Hit the key and the gauge goes down hard - way below empty.
I spent extra money on an AC Delco sending unit. It was made in fricking china.
Did I get a bad sending unit? Any ideas?
The sending unit would have had to just go bad when we put the sending unit and new fuel tank in. It worked somewhat before. It would only go to 3/4 tank when full and go to empty way before its time.
The sending unit is in the tank. A learning experience for me that I didn't want. Seems like it would be a dang good idea to plug the sending unit in and move the float before installing it in the tank and installing the tank. I learned years ago - the hard way - to test new alternators and starters before installing them. I must be slipping
The pump is good. On a diesel the pump is not in the tank
There is no ground from the sending unit to the frame. There was no ground on the old unit either. all our other 6.5 diesels have a ground to frame off the sending units. Neither the old nor the new sending units had a ground wire.
There is a 2 wire plug to the sending unit - I assumed power line in and line out to the gauge. Not sure exactly how they work.
I am planning to hook a ground jumper wire to the tank tomorrow. Don't know if I can get to the sending unit to hook the ground directly to it, with out dropping the tank at least some
Any advice would be appreciated
