Installed in my new tank, but once I got the tank installed it wouldn't line up with old fuel line. Had to bend to make it fit. Not sure if it is tank or sending unit, but it is in.

Easy instae
Great deal with the item I was looking to replace, but was going to save a few bucks so I could afford it. Luckily it went on sale just as I needed it, or was going to have to wait to purchase it. Awesome! I now have a functional fuel sender.

Fuel Sending Unit
The unit came and was well packaged. No damage in shipping. It was a quality unit, but the fuel outlet was about 45 different than the original 1966 part I removed. That made plugging the electrical connector back on a bit challenging. Had to use a little Permatex to get the gasket to stay in place. About a two hour job for most.

Crome filler tube
It nice to not having to worry about rust getting in your gas tank. This unit fits just like the factory unit and being crome gives it a little more pazzizz.
