Q: So the only Foxes sold there officially by Ford were the 1979s? And you think there were only 400 of them?
A:Yes '79 and only in 2.3l Turbo. I had this information from a friend, founder of the Mustang Club de France, owner of one of the oldest running Mustang (VIN #145, car of movie "Le Gendarme de St-Tropez" and many french video clips and soaps), a guy who has one of the highest knowledge on Mustangs in France ... I have no official information from Ford France, they send me back to my club
What is the story on your particular car? What has been done to it that is necessary for legalization in France, and do you have pics?
My car was sold new in Switzerland in Nov, 5th 1979, licensed Dec, 22th 1979 ... I guess it was a show-room car as it had all graphics installed and was sold pretty late (i haven't tried to contact it's original owner, but I have his address in the Ford Service manual, so maybe one day when I'll ...
Necessity being the mother of invention, I recently set about to find a way to repair the fuel gauge sender on my '85 CFI Vert.
The '83-'86 CFI and EFI fuel gauge senders, Ford part number E3ZZ-9375-C, are no longer available from Ford, and none of the usual sources are able to find NOS ones anymore. What's worse, they are not reproduced by anyone in the aftermarket, even though they seem to have a higher failure rate than the senders for the carbureted cars, which are reproduced. I don't know if it's because the people selling the senders are unaware of the unique nature of these senders, but whatever the reason, I really like having a gas gauge that works.
The '83-'86 CFI/EFI sender is very different from the sender for the carbureted cars. It's actually a lot like the sender for the '87-'93 cars, but the resistance range is 80 Ohms empty and 10 Ohms full, while the '87-'93 sender is 10 Ohms empty and 165 Ohms hen the tank is full. Since I wasn't having any luck finding the E3ZZ sender, I started looking around for other Ford senders that could be used as organ donors, to repair my existing sender.
The CFI/EFI style senders use a ceramic printed circuit resistance strip, unlike the wire-wound resistor elements in the carbureted cars. Over time, wear and corrosion from oxygenated fuels take their toll, and the result looks like this-
For this particular sender repair, I ended up finding a donor from a very unexpected source. Dorman Factory Solutions makes a line of factory replacement fuel gauge senders, and the one I used is for, of all things, the 1984-1987 Tempo/Topaz, 2.3 Liter, without fuel injection. Who knew? This sender is Dorman part number 692-120, or Ford part number E63Z-9275-A.
Here is the donor sender, alongside the original unit from my '85 (the grungy looking one).
The senders are very different, but that doesn't matter, because we're only going to use one part. Well, maybe two, if your original float is not serviceable. It may be possible to use more of the parts from the donor sender, but there are differences that would make that a bit more work. More about that in just a bit.
First thing we need to do is take the senders apart. The float arm is a press fit into the old sender, and will need to be pulled out before removing the sender cover. I used a pair of needle-nose pliers to gently lever the arm out of the wiper. On the new sender, the float arm is a bit easier to remove. Once the float arms are off, the housing unclips from the metal backing plate, leaving you with something that looks like this-
(Yours will still have a wire soldered to the resistance strip.)
The new sender had some of it's pins heat-smashed on the back side of the plate, but once I trimmed those, I was able to unclip the housing just ...
