ThankAgain... If the oil and temp gauges operate as they should, the mechanical limiter is not the problem.
My guesses as to where the problem is... The wire to fuel sender is dark blue and placed at 12 o'clock position of the round harness connector. I've seen the wires placed in wrong ports of that connector causing strange conditions. Some of the factory wiring diagrams are drawn confusing. The connectors key is physically at 12 o'clock position yet is drawn rotated 90 degrees. Some of the aftermarket/homemade drawings are wrong also.
I've seen the contact posts shoved through the circuit board. I've seen gobs of solder on the back of the boards too. If the sender wire intermittently makes contact to ground, the gauge goes to max 'F'.
So the sender signal on that blue wire is my first guess. Fault somewhere between the inst' panel and the senders contact post.
I've also seen gauges that stick intermittently at the off/home position. The winding on bi-metal beam coated in nastiness can effect movement like a cast on a arm. Needle itself distorted ( poor/improper handling ), etc...
DO NOT TAP ON THE LENS! Good luck with it.
