I have the 7822 fuel sending unit in my boat, does anybody make a direct replacement for this sending unit or do I have to purchase it from Fountain.

I had to replace mine years ago and found the supplier to Fountain. I'll look around to see if I still have their name.

Also, be very careful when you start removing the sending unit. You have an aluminum tank with an aluminum sending unit. The threads can gall easily. I found the best way to remove the unit is to:

1. Spray penetrating oil on the threads.
2. Vigorously tap the assembly with a hammer as you try to unthread the unit. The impacts will help the unit unscrew. If you have trouble adapting a removal tool, I actually have one that was fabricated to go over the unit with a 3/4 inch socket attachment.
