I have the autometer classic gauges and the FFR fuel cell. I've searched the forum and the sender and gauge is wired correctly, power, ground and sender wires. The gauge won't move off of empty. Any ideas on hoe to test the gauge?
If the sender is the same that Fuel Safe has used for years, it's a Centroid Products sender that needs to be calibrated. Here's the instruction sheet. There's some little pots on the top that you need to adjust.

The gauge seems to be stuck on E. I have disconnected the send wire and get no movement, I have also disconnected the positive wireat the sender, still get no movement? The gauge is an autometer vintage with resistance of 16/158.
I'm pretty sure the 16-158 ohms gauge is compatible with the Mustang (donor) fuel sender. Is that what sender FFR supplies with their tank? If not, you will need a different gauge, or a new sending unit, (unless yours can be calibrated as Ron suggests).
Well, it's working. I pulled the gauge to verify proper wiring (all was fine), reinstalled it and it is now working. I must have had a short or a bad connection at the gauge. Thanks to all for the replies
