I replaced the fuel sender with the replacement one today and the whole job took around 20 minutes. I took photographs which can be seen
here. The gauge works fine now and finally I can tell how much fuel I have in the tank. The replacement fuel sender cost 44 bucks for a used one. A new one seems to be around 170 bucks. I like this 944 as the parts are cheap and I can work on it myself which saves on labor. Next up today is an oil change with new filter too.
