i'll try that test thank you. I did a LS swap and I ran a 87 sender I switch out the pump on it so I'm sort of wondering if I possibly discounted the wire on the sender. everything is brand new or I got a bad sender. I just filled my tank Friday so its going to be at least 2 weeks before I can pull the tank to check the sender. unless I cut a hole in my bed. I forgot to mention this is on a 75 chevy blazer which I'm sure is the same as a truck
