Here is a quick rundown of my fuel sender install for all that were curious:

THe sending unit and guage is still available from NAPA and is part number 501-1742. It is an adjustable sender and will fit tanks from 5-27 inches deep. It comes with the sender, guage, the guage mount if needed, the gasket for the sender, the sender bolts (very important and you'll see why in the pics) and all instructions to do it. The resistance for the sender is Empty: 240 ohms and full 33 ohms. The price was $41.00 out the door. Here's the kit:



Here is the top of the sender to get an idea of the bolt pattern. It fits the tank perfectly:



This is the guage after I painted the ring OD:



This is why the new mounting bolts were so important. Every single screw broke off in the tank. A little skill in drilling broken bolts doesn't hurt either:



Here's the screws drilled, and the mounting surface clean:



And lastly, the new guage installed in the dash:



Tomorrow, I will post the rest of the install after the tank is ready to go in.
