I'm closing in on an elusive EVAP leak code on the Expedition. I smoke tested it and found that it was leaking somewhere on the top of the tank. Waited for low fuel and dropped the tank and found it wisping out from around the pump/sending unit o-ring area.
I got a new o-ring at O'Reilly today and plan to replace it tomorrow if the weather allows. While I'm in there I want to try to clean the fuel level sensor, the gauge is not reading well when it's above 1/2 tank.
I know Techron is the go to when the sending unit is in the tank. Will something like DeoxIt work on the sending unit while it's out of the tank or are there better options?
