Some Feedback.
It’s taken a while because I don’t yet clock up a lot of kilometres in my Patrol.
I fitted a heavy duty extra battery to chassis earth cable as Yendor suggested & have now run a full tank of fuel through the motor. I am most pleased to report that like Rafa’s experience, the additional earth has fixed the problem, & my fuel gauge now reads ‘normally’ It’s great to once again have a gauge I can rely on.
Thanks Rodney.
