Fuel Pump Testing

Since I was able to verify that the fuel tanks don’t leak like a sieve, the next step was to pump fuel through the fuel lines and totalizer, to flush out any junk, test the totalizer and make sure it was talking to the Dynon Skyview. Mission accomplished. Both sides tested and everything appears to be plumbed correctly. No fuel odor detected.


The Airflow Performance fuel pump was able to maintain between 39-40 gph the whole time. I pumped about 4 gals through each side. I pulled the fuel filters expecting to see some junk, but there was nothing in the filter. I guess I can’t complain.
