Question about fuel sending unit.
I ahve a 73 cj5 and i think i might need a new sending unit, I wen to the posts about the guages and tested my guange and it worked. the thing is is that the guage does register having fuel in ther tank like it will go up to quarter or half but its not accurate. Liek the other day it was at a half tank and i ran out of gas. Sooo what does this mean?
