many threads on this board about them. almost none of them seem to work. i have put a couple of hours into messing with mine, and can't get it right. on the bench everything seems perfect. put it in and it's at least 1/4 tank off. almost everyone says that, 1/8 to 1/4 off.

talk to bill at AM HighTechAuto, (a member here), amhightechauto.com. he will know who is making the better ones out there, for whatever that is worth.



Mine I bought last year shows 1/4 tank when it's dead empty, and full at anything over 1/2 a tank.

When I measured it I think it showed 11ohms empty and about 78ohms full which I've been told is close to the factory senders, so I don't know why it's off so far. I was wondering if I could add resistor inline with the ground wire to get it to read closer to correct?
