Attention: TDR Forum Junkies The fuel sender is less than three months old. I installed it because the old one stopped working one day. Or rather, I ordered a new one because it stopped working, but then I took the old one out and cleaned it and it started working fine but I put the float on backwards so it was reading way off, which I didn't discover until I went to install the new one. Since I was that far along, and the old one was probably the original, I decided to swap it anyway.
So I have a ~2 month old fuel sender that has worked perfectly for over 2000 miles (commuting to work and a weekend trip to Sacramento from Seattle).
All week my low fuel light has been coming on and off because I'm getting low on fuel, then last night it came on solid, so this morning I stopped and put 30 gallons in.
As SOON as I fired the truck up after filling it, the gauge dropped to zero like the sender was unplugged. It bounced up to just above the E mark once, then dropped to zero again and was there the 4 miles to work. When I got to work, I shut it down and cycled the key four times and each time the gauge came up sharply and solidly to different levels, none of which was full. At lunch I went to visit a friend and the gauge went from dead full (where it should be) to unplugged empty (with accompanying low fuel light and annoying chime) no less than six times.
I hadn't drawn any correlation between getting fuel at this station and my old fuel sender going out before, but now I'm wondering if it isn't something in their tank/additive package that is causing loss of continuity in the sender.
There was a film on the old sender I took out, and when I cleaned it off the sender worked perfectly.
Has anyone come across this before?
