Fuel guage and sender install

[randyscycle]

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.

Outstanding detail, Randy! Thanks!

Same one I'm using, only a different gauge. Keep the pics coming.

Thanks for the info
Is that a 12 volt or 24 volt unit?

I am going to replace my sending unit also. I have the unit but no gasket but since NAPA makes the unit you picture, I hope they also have just the gasket. I saw some gaskets on e-bay this week and they went for $28!!! More then I paid for the sending unit! Thanks for the info.

That is a 12 Volt unit, and I am not sure if they make it in 24, but because NAPA does a lot of equipment parts, I wouldn't be surprised if they do offer it that way too.

The gasket is rubber and doesn't look like anything special, so in a pinch I suppose it could be cut out of some heavy, chemical resistant rubber. Its about 1/8" thick. The original looked to be rubberized cork, but was so deteriorated it was hard to tell.

The guage in the picture in the catalog was different than the one I got. I guess they farm out the supply of the guages. I wanted an orange needle to match the others, but no big deal.....I bought one of these kits a year or so ago for a boat I was working on, and it had a totally different guage as well.

Here are a couple more pics of the sender install:

Here is th esender actually bolted into place. The tank has been coated with POR:



Here is everything in its pretty OD splendor:



I am going to post another thread showing my fuel pickup mod in a few.
