On what? What type of sender? Sure you have a sender problem? Our mind reading thread was shut down. Lack of users.
It depends on what gauge you have and what ohms it reads. Why not buy the gauge manufacturers sending unit, they're not that expensive?
Replaced mine with universal unit. not expensive. Take old one out, may have to cut new one down to match old one. You may have to match up float rod. Toughest part was taking cabinet apart to get the sending unit out. Most of these jobs are easy, its just working in small confined areas.
