'72 Scamp

I had massive amounts of rust in my gas tank and opted to replace it. You can find new reproduction tanks and sending units for under $200 if you look around ebay. I decided to replace it after I looked around at fuel tank rust treatment options and found that to do a tank this size the good stuff was going to cost me around $150 anyway.

That sending unit having 1/2" line may be overkill for your application, but you get the idea.
