My 79 Corvette needs to have the tank sending unit replaced but I want to know if it is possible to replace it from the top of the tank through the filler door?
After taking the door and rubber sleve out, the diameter of the open door looks big enough to angle the unit out of the tank instead of dropping the tank to replace the unit.
Yes, it should pull out the top. I was able to on mine. Not sure if there is a difference in yours or not. Im sure some folks will chime in.
It will come out from the top on my 79, as you pull it out, rotate it around to remove and reverse to install. Don't forget to install the rubber gasket.
I just wanted to hear form others before I tried to take the sending unit out. This way will be much easier than dropping the tank out just to replace the sending unit.
