We consulted with Glasair Aviation to find what the nose-up angle they used to test fuel flow to our Lycoming O-360-A1A carbureted engine. Our engine requires 14.8 gph at 2700 rpm full power. With the boost pump on, we had to measure 125% of that fuel flow to meet the requirement. We were told we must have the nose up 18 degrees with minimum fuel in the 15 gallon main tanks. My partners accomplished that by using a small tractor with a front end loader to lift the nose wheel while the tail of our Sportsman was over a ditch allowing the Sportsman to reach 18+ degrees. (Note: in the photo below you see our digital level taped to a 4-foot bubble level taped exactly on the waterline marks we scribed on the fuselage years ago in the building process.) The test was successful with the boost pump running. Our engine has Lycoming's engine-driven pump and now has a boost pump installed in the 3/8" aluminum fuel line between the Newton V1-3P-C FAA Conforming 4-position fuel valve and the firewall in the cabin. As an extra precaution in case the boost pump fails, Stratford installed a Facet 48108 electronic pump in the fuel line under the tunnel cover. That pump has flared fittings, so the job was particularly difficult. Hooray for Stratford and my two other partners who helped. I was at home working on uploading photos like the ones you see in this building report.
