Scout 80 Fuel Sending Unit..... Yeah I was bored.

Well over the chirstmas holdiays I was getting a little bored. So I decided that I would address somethings with the Scout. (mods if this is the wrong place please move it, thanks) a little history. I purchased the Scout about 2 years ago from a guy that had for about 12 years; 10 of those were just sitting to rot. Or sitting waiting for me to come save it. I pulled the tank out about 2 months ago and found that it had about 3 gallons of use to be gas and about 5 gallons of just pure water. Naturally all four bolts on the bottom broke off. Pulled the tank out and removed the sending unit and dip tube. Both rusted pretty bad.


Well I decided to see if I could save the two. The sending unit worked back and fourth but sounded like it had sand in it. I looked in over and found that it was made so it could be taken apart. I removed the cover and found about 40 years worth of rust inside.

And the mechanical part looked pretty good. So I started cleaning it up. Got most of the rust cleaned up and put back together and works pretty good now.

One thing that I have noticed working on this thing is that back in the day; most things were built where you could rebuild it instead of the throw away and get a new one mentalilty there is today.

Then I looked at the float. It was brass but you couldn't tell it by looking at it. It was black and tarnished. So I cleaned it up looking for holes. After I got it cleaned I found 2 that needed attention.

And the other one.

Now this is a two piece float that is soldered together with soft solder. Well putting my hvac skills to work I cleaned the holes as best as I could and soldered them up.

Now I must amit that it was not as easy as I thought it would be. But I did it. That brass is extremely thin and you could burn thur it fast. I tested it and it has no holes even though that last picture looks like it does.
 
I've delt with this many times myself josh!

But all the senders I've attempted to rejuvenate had the wipers worn completely down and the windings have been open.

New floats are no problem to obtain. Some are straight brass, some are brass/plastic composite. This same float was used in hundreds of variations of these senders over the years (most especially many Ford apps)...some are still being used in marine tank senders today.

Iho has 'em in stock, same price as what I pay for 'em locally at the parts jobber:

fuel tanks and components

Iirc, ihon also has 'em on hand. These floats do not work with the current replacement version of the s80/s800 fuel sender we source from light line however.

Those senders were oem-supply to ihc and other manufacturers by introl and stewart warner.
