I'm very disappointed about my new gauge for my 66 GT convertible.
I tested it in all way outside the fuel tank and the gauge on the dash move well from E to F.
Inside... the gauge don't move before 30 liters and stop to the middle with the fuel tank full.
The wiring is perfect, no resistance.
I heard about bend the spindle to adapt to the fuel tank, is it really the way to fix this problem?
