This is the gas tank level sending unit for all 2wd Vanagon from 80-92. It is also called a fuel tank level sending unit, a gas tank level sender, a gas gauge sender, and a fuel gauge sender. I am also including the word sensor for search reasons. This sender only works with 2wd Vanagons. If you have a Syncro try PN 251919051H. Located on top of gas tank.
