How weather proof/resistant is a weather pack? I ask because recently my fuel gauge started acting oddly, jumping here and there. I separated the weather pack connector in front of the fuel tank. I measured resistance on the sender, which read 40 ohms--about half a tank which was correct. I grounded the gauge itself and it maxed out. I thoroughly cleaned the weather pack connections with electronic cleaner and currently the gauge seems to function as it should. Could the weather pack be the culprit for our infamous fuel gauges problems?

Well i dont know. Having unclean connections can cause problems though. I had a in-tank fuel pump not work because the connection inside of the tank was dirty. Cleaned the connectors and it worked just fine.

Curious what you used for "electric cleaner"? I usualy scratch the connections with a knife, use sandpaper, isopyhol alcohol or an eraser.

 

I did probe the connections with the pick end of a test light and multi-meter, then sprayed CarQuest's Quick Dry Electronic Cleaner in both halves. The spray is supposed to remove oil, grease, dirt, flux and other contaminants and to help prevent contact failure.

By the way, I did try a second gauge before checking and cleaning. That gauge (one I had laying around, so I'm unsure if it worked correctly from the outset or not) acted even more bizarrely. When I filled up, the needle settled about a quarter passed full, then remained there for well over a hundred miles--symptoms I'd read about in a search. This gauge showed no improvement after the checking/cleaning. The original gauge, however, seems to work fine now--or at least as good as it always did.
