Hopefully not a dumb question.

You're going to have a difficult time finding OEM Chrysler parts.

That said, I always chuckle to myself when guys ***** about the accuracy issues of new parts. Here's the thing. Like everything electronic and Chrysler.......it SUCKED. All those factory gauges are just approximations at best. Just to give the driver a general idea of what's goin on. The biggest thing to "ME" is knowing where empty is. As long as that's pretty accurate, I'm good. Best thing to do there is carry a can of gas in the trunk and run it out. That way you'll KNOW where NOT to move the gauge to again. lol
