Installed this in my 89 Stang LX and had no trouble. Make sure to clean the old Dialectric grease out of the harness conector, and put new grease in the conector. This will prevent any conection problems.
I bought and installed this fuel level sender last week. Works perfect so far. Came with seal and new lock ring.
Bought this unit because it was cheaper than the factory ford unit. The unit does not read correctly. The guage stays on full until the tank has aroung four to five gallons, then the guage drops to half a tank. Never ran the car past the point to see where the guage falls next. Save your mony and order the Ford factory replacement. The work invoved to change it again is not worth the savings in my book.
Quit working after two weeks.
Had this installed in my 87 5.0 to fix my inop fuel gauge. Works like a charm now. The shipping was fast and the product was great.
