How do you ground the fuel sending unit
'71 FJ40. The electrical wiring schematics do not show the sending unit as being grounded.
I have good 12V contacts at the fuel guage (original) and when touching the sending unit side of the guage to a ground, the needle goes toward the battery side as I believe it should. The guage is not close to accurate. The sending unit has no location for a ground. Is it supposed to? The P/O tried to ground with one of the screws around the sending unit...which has no effect one way or the other.
Thanks in advance....
