In my 60 years of automotive experience I have never seen a fuel float is such bad condition on cars or tractors.

What do you attribute that to? Is that a domestic manufactured brass float, or a golly-knows what pot-metal deal? If the former I'm figuring it's due to ethanol??

 

I'd say it's from water. Looks like salty water??

 

Truck was last running in 2008 so I don't know how much ethanol was around then. I wouldn't think water would do this to brass but who knows.

I have put on a new float and will see if the sender unit makes it.

I've been playing with this stuff for that long as well and I've seen nothing like that.

 

Maybe it was being run on drip gas

 

Ethanol laced gasoline has been around since the 70s or 80s afaik. How do carb innards and float look?

 

I think I see your problem. Someone replaced your float with a basket.

 

My origional float was riddled with holes - something in there likes to eat brass.

 

If you hook an ohm meter up to it you should get some kind of a reading as you raise & lower the float shouldn't you. I am getting nothing so I guess I have more problems than the float.

Got another truck so I may pull the float gage and check what I get on it with an ohm meter.
