So .. the one I have has a 1/2 inch of gunk in it.... has lots of pin holes (mostly in the top) that need to be brazed / plugged. The float sensor is in pretty rough shape and will probably no work. So, given that I will probably not be taking the Darrin on any long trips, I am not all that concerned that I know how much gas is in the tank. Wouldn't it be cheaper just to fix the pin holes over buying a NOS or a HJ tank that may have just as many issues?
