Don, your catalog listing for 69-70 senders say they are for a 16-gallon tank. Fuel capacity for these is 20 gallons, 22 for a 70 without the evaporative emissions stuff.

Yes, I will get them dialed in. My data input guy misses stuff from time to time. Good eye!

In any case, you can buy the T Bird sender and swap the important parts (thermistor, sending unit, filter sock, and float) to rebuild your original cheaply. Click here to see the T Bird unit that you need to buy:

Do you know if the sender unit is correct for Cougar gauge. The repro Mustang one doesn't read correctly on the three gauges I have tested. Mustang one goes full ok then drops to the empty mark (before the red area) when the tank is half full

If it shows empty when the tank is half full wouldn't it only show half when the tank is full? Mustang repro senders were tested out of the car

I have a 22-gallon 70 tank in my 69, using the 69 (20-gal) sender. The gauge stays on FULL for a long time......

You must have got a bad one if that is the case. The Mustang repro senders are of course the same as standard Cougar senders, and the reproductions are just as good as the originals from my experience. Good product, I think Scott Drake is the only source.

No, there are at least 2 suppliers for the single prong sending unit, ACP being one of them and I believe carpenter being the other and yes Drake does repackage. We get a lot of returns on repro sending units, less now than years past but they still are not as good of quality as FoMoCo units.

I had a similar experience with fuel senders on my 1968 1/2 Cobra Jet Mustang. After installing two repro senders, both of which would read half full when the tank was full (one of which was a Scott Drake), I finally bought an NOS Ford original which of course worked perfectly. These were the single stud units as that car did not have the low fuel warning option. I have high hopes for your low fuel warning repro unit Don. Thanks for all you do.

Ordered mine yesterday with the low fuel warning. Looking forward to having everything back to normal.

It is great that WCCC has gotten quality repro's (better than OEM actually with stainless construction). A Cougar reproduction product that is long overdue.

I want to mention however that "back to normal" for this sub-system means annoying flashing of the LF lamp at the low fuel threshold. Only the Electronic Low Fuel Indicator (ELFI) kit corrects this condition with significant hysteresis at threshold, effectively eliminating flashing. With the ELFI, the LF condition must exist for ~1 minute before the LF lamp will be illuminated. Similarly, the lamp will not go out until the LF condition is no longer present for ~1 minute (ie. more fuel is put into the tank).

Unlimited technical support is also provided with the purchase of an ELFI kit.

Disclosure: I am the designer, manufacturer and seller of the ELFI kits. WCCC and NPD also sell them (but I have the best deal on them!).

Thanks WCCC for all you do for the Cougar owner, we appreciate it!
