First off, I'm sorry. I'm sure if I did a little more research I could find the answer, but I have to go to work and I'm super impatient. With that aside, I have been driving my 1973 dart custom for almost 2 years now. My last older vehicle had a bad fuel gauge the never quite made it to full or back down to empty, and unfortunately I didn't find this out until I was sitting on the side of the road on a 110° day. As a result I've just played it safe, and never let my dart dip below a quarter tank. I've done all the important drive stuff and I'm now working on the smaller things and I'm wondering if there is a way to confirm my fuel gauge operation that doesn't involve waiting for it to sputter out on me. Thanks as always Ps when I fill her up the gauge does make it to "f"
