70-10 ohms

My buddy was telling me that my rangers sending unit is 70-10ohms and that most chevys are 0-90 ohms? Is this true?

yeah fords are reverse. look up fuel sending units at jegs.com

you can read all about it

0-90 ohm senders fit most GM vehicles 1965 to 1997. Will not operate on some 1998 or later vehicles with 40-250 ohm senders.
70-10 ohm senders fit most Ford vehicles before 1989 (except 1987 & later Mustangs) and most Chrysler vehicles.
240-33 ohm senders work with most aftermarket ''universal'' fuel level gauges.


It says before 1989?
