A single overflow line went from high on the back of the fuselage tank to the right wing tank, which then was supposed to equalize with the left tank via the balancing line between the fuselage tanks. Replace- ment steel tanks of identical construction and plumbing were manufactured and sold. A fuel tank gauge (on the right wing tank inside the fuselage) was vented "by fitting on side of fuselage" Ercoupes from Serial No. 2623 thru 3220 substituted a stainless steel fuselage tank of "identical construction" except that the single overflow line went from a standpipe connection in the bottom of the tank to a tee in the balancing line between the fuselage tanks, which were now aluminum. These tanks could also be installed to replace earlier ternplate wing tanks with appropriate plumbing changes, and had a single, unvented fuel gauge in the left tank (also inside the fuselage). Ercoupes from Serial No. 3221 thru 3467 again had a single overflow line from high on the back of the fuselage tank, but this now went to the left wing tank, again to equalize with the left tank via the balancing line between the fuselage tanks.
