Mine was installed right after the car was purchased and the hole for the hose was straight down and through the floor. I filled it half way because it was what I could to to keep the seal from leaking. They are known to leak. As a restored car, I will probably never have a need to fill it to 34 gallons but before I re-install it, I do intend to figure out how to get a better seal where the bucket joins the tank.
BTW, does anyone know if the tanks were painted black or were they originally bare galvanized? Thanks
