I've got the WCCC "Fuel Sending Unit - Low Fuel Sensor - XR7 - STAINLESS - Repro Item #: 18901". They are currently out of stock. The level calibration is way of as reported above, I'm disappointed that WCCC didn't indicate that would be an issue. They are usually good about that. It has three posts (two electrical connections and one locator). I replaced a prior after market sender (w/o the low fuel sensor) that had only the one connection. It appeared that the connection on the aftermarket sender was larger or forcing the three connector wiring harness plug on the the single post may have damaged the harness plug. That prior aftermarket sensor was reporting fuel level fairly well but I wanted the low level. I have issues getting a good connection, the connector doesn't fit tightly on the posts, the low level sensor is not working reliably and I have run out of gas once. I've ordered the MeterMatch-VR and will try it out next time I feel like pulling the dash pad and instrument panel and rewiring.
The reason we did not report that these units had issues is we did not know... The supplier claimed they worked perfectly in the T-Birds for 2 years and had been thoroughly tested. We were thrilled as all they had to do was put a different tube on it and it was correct for Mustang / Cougar. We were grossly misinformed, they had multiple problems and we will not relist them until they have been in our cars (plural) for 60 days with zero issues. So far that has not been the case.

This would be a great topic for a tech article. I pull the sender out and then plug it in with a ground wire run to the tank. I put the arm fully down and verify the gauge shows empty. Then I put it all the way up and verify that the gauge shows full. There are limit tabs built into the sender. by slightly bending the tab and the arm I am able to get it read right at both ends of the scale. Where it is in the middle isn't a huge concern at least to me. In almost every case I am able to replace the thermistor, sand blast the winding's, clean it all up and smooth it all out with fine emery cloth and replace the float and filter and it all seems to work for the next five years.

I should add that Bob's ELFI works even better than replacing the thermistor.

I bought one for my yellow 68 XR-7 and I can't get it to register full either. Don, will there be a "fix" for those of us that bought these before the problem was discovered?

If no fix then a refund... We are hoping for a fix.

I'm hoping for a fix as well. I think I must have bought one of the last ones before you found out they were having problems.

Don,
Sorry my criticism came across too strongly. You guys are the only supplier I know of that screens and rates products including offering those that are the only thing available but have issues that you caution about. It is appreciated. Many of the sending units have issues from a linear versus non-linear outputs and it's about impossible to tell how they will work. I'm expecting to get the MeterMatch-VR shortly and that should (if as advertised) let me calibrate the gauge readout to accurately report the fuel lever. I''ll let everybody know how it works out.

So, at the end of the day, there really is no good fix on this right now it seems. I suppose I can just use guess work. Fortunately, the trip odometer in car works and I reset it last time I topped the tank off. I'll keep a close eye on fuel mileage, knowing the tank is 20 gallons, and go from there. I just have to remind the wife if she fills up she'll need to reset the trip odometer so we can see how far we've gone since the last fuel. Or, go REALLY old school keep a gas in car at all times.
Hippie gas... that's funny. Lucky for me, I can get non-Hippie gas where I am at, which is what I will burn exclusively in the car. But I expect any damage has already been done.
