Got car ramps to incline to fuse as much as possible. Needed to instal bolt inserts to place in front of the ramps or else they slipped fwd as the winch drew the mains up the ramps. Once on the ramps and chocked, winched down the tail, then put a jack stand under the nose fork. (Image 1).
All that work...+12.25 deg deck angle. Did 1 and 2 minute flows into a 5 gal jerry can (tare wt. 3 lb) from right and left tanks. Then turned the overflow fitting 180 degrees so the top of the Tygon tube was +20" above the inlet to the engine-driven fuel pump. Did 3 minute flows from right, then left tank. Indicated flows from the Red Cube were about 38 gal/hr in all cases. Measured flows were all more than 2x the FAA recommended 125% of full-power flow for fuel injected engines.
