My first thread on this was locked by the moderator so here we go again. :nonod:When I installed the new sender and filled the car I noticed that it didn't read full. Well I was below E today and when I fill it it only held 10 gallons and read 1/2 tank but the car was full. I drove straight back home and measured the resistance at 21 ohms. Does someone have the specs for the ohms rating of the sender on a 66 Mercury Cyclone.
