No.. The sending unit is on the lower drivers side. You need to drain the fuel and use a wooden or brass punch to rotate the sender ring (dont use steel as you may get a spark, not good with the fuel around.
Then just slip in the new sender and use the brass punch to rotate the ring.
I had to do mine twice last year, I sprayed the lock ring with pb blaster, put in new unit with plastic float---lasted a month , got one with brass float---works fine ---plastic was full of pinholes, ohio mustang has brass ones I believe,the tank does not have to come down---just siphon most of the gas out---pretty easy unit to change
Hmmm! I've got a 67 fastback with a new unit sitting in my garage waitng for me to climb under. I never replaced a fuel sending unit and I have a quick, probably stupid question-----Does the sender ring have a regular screw thread(like a large nut), or does it have a limited travel type (like a gas cap lockdown)? I just want to know what to expect, since I'm not too keen on working under the car with those gas fumes. The faster I get out of there, the better!!!
