Over the last three months, my Low Boost Pump has been misbehaving... (1) turn the switch on, it runs for a while and stops intermittently... (2) the intermittent stopping got to be longer and longer... (3) earlier this week I hit the switch and nothing happened... (4) the High Boost works as usual... (5) the high Boost cannot replicate the LB's abilities. LB can run continuously while the engine warms up. (6) the engine dies at least once after start without the LB continuously running. (7) I take the plane to see the mechanic. He pushes the LB button, it works fine... (8) I get a brief lesson on the adjustable pressure setting related to the low boost switch and what I might expect to do if the 1.5 AMU pressure regulator needs to be swapped out... (9) I look forward to going back tomorrow to push the switch again. (10) total run time on this pump is about an hour total. 15 seconds per fight... (11) there is no fuel pressure gauge in this modern O. My question... Any of you fine Mooney pilots have difficulty with your LB switch not turning the fuel pump on? Maybe it just needs more exercise, -a-
