Progress this W/E: I added tri-stock, stiffeners, wing saddle doublers, and lightening holes. Refurbished old Sullivan tanks with new bungs; 1 oz (really > 1) will go to the rear, and 2 oz will go up front, fixed pickups - under water tests are probably better but I did my usual lazy pressure test - cover vent, blow into supply hose & pinch, count to sixty, and release near my ear - if I hear a decent rush of air, I okay it.
Would like to know this: does vent line pointed into or away from the airstream help, hinder, or cause no affect to engine runs?
