33 While all that's seemingly left is to tackle prep and paint in order to finish the tank, not to mention some mounting bracketry, there is one further item required. The old sender had more than one use throughout the sealing process, but is now ready to be consigned to the trash. Using a hole saw I cut this disc from 1/8-inch steel, and will drill it to fit where the old sender was, as well as to take a Russell AN-8 bulkhead fitting sourced from Summit Racing. Stainless fuel line will carry the gas to the motor. And if you're wondering how I'm going to vent the tank, I plan on drilling a horizontal hole in the base of the filler cap under the hinge and running a brass or nickel-plated tube from there.
