Sending unit

Lots of gas tank sender threads on here. If you buy the aftermarket ones that are not designed for the shape of the tank, they work poorly. Mine has an aftermarket sender that is linear and my gas gauge reads full for a long time, then goes to empty very fast. It still has about 1/2 tank on empty. The factory ones are non linear. Read up before you do anything. Fewer options after you get the sender installed & doesn’t work right. I am thinking about buying a meter match.
