Gas Tank Sending Unit Question

[Dean]

Ok, now I'm confused. The last thing not working on my green K20 was the fuel gage. I determined that the sending unit was bad and removed it. I have at least 5 other sending units from other trucks and they are all different.

The tank in my green K20 was out of a 70 truck. It has a fitting on it approximately 7/16" in diameter. I had one out a 71, but it had a bigger fitting around 5/8" in diameter. Some of my other ones appeared to have a rubber hose connection.

I guess I haven't paid that much attention to these things over the years.

Did they change the fittings over the years? Can I get one to fit the 1970 fitting (~7/16")???

Thanks!
