Today I checked the output of the electric boost pump. The IO-360 engine uses .55 lbs of fuel per horse power per minute to produce full power. After doing the math, the engine needs 16.5 gallons per hour for full rated power. It is recommended that the fuel system be able to provide 125% of this to the engine, which is about 20.6 GPH. Today I tested this.
I disconnected the fuel input hose at the fuel injector control servo and attached a spare hose and ran it to an empty fuel container. I then turned on the boost pump and let it flow for one minute from the left tank. I then measured what the pump was able to put into the container and it was .8 gallons. I repeated the test for the right tank and it measured .81 gallons. These were done with the airplane in the on-ground attitude. I then ran the main gear onto blocks and repeated the test at a 13' nose up attitude (the maximum I could safely raise the main gear) and the results were the same.
The math on this is that the boost pump provides 48 gallons per hour which well exceeds the required 20.6 GPH.
