With both fuel pumps running (on the ground or inflight, any power setting), turning off pump 2 results in a momentary (approx 1 sec) power loss. RPM decays and fuel pressure drops. Comes right back. Does not happen when pump 1 is turned off.
Good steady fuel pressure single or dual pumps.
Suspect #2 check valve slow to open.
Using 93 octane ethanol free.
Any ideas?
