So, I drive an old 1997 jeep wrangler with a little over 150k miles. My gas gauge has stopped working. It will bounce between empty and full with no in-between. Occasionally the fuel light will come on but it happens usually right after I fill up and its only happened a handful of times. I recently had my fuel pump replaced along with a few other non-fuel related items. I was told by the dealership that the part I needed was no longer manufactured. I've just been filling up every 100 miles or so but does anyone know how to get a working gas gauge and about how much it should cost or how hard it would be to do myself.
