Why should we have to buy a 2nd tag a long component to make haphazard aftermarket stuff work? The one in the 80 d150 and the 87 ramcharger still have 1/2 tank when they read empty, the one he bought for the 72 fury shows nothing at all. Pure junk
There used to be companies that advertised a service where the rebuilt original sending units, always wanted to try one of those places but lost the contact info that I had for one in Ohio
