Bear with me, low time pilot ,new maule owner.MXT-180. I have read the POH BUT am getting dif. storys from the previous owner, mechanics etc. When do you use the boost pump? start up?takeoff?landing? switching tanks? or emg start only as I think I read in the POH?No pump in the old 172.
more questions under appropriate topics later
Thanks

I have an 85' MX7-235 with a Lycoming IO-540 I use only at start up especially cold. Full rich and full throttle setting turn on pump for a few seconds until flow is indicated then off. As I understand, it primes for cold start , clears lines if vapor locked , and will back up mechanical pump if fails. Just had my Dukes boost pump overhauled 600.00 at Oklahoma Air.

Carburetted Maules use the Dukes fuel boost pump to retrieve fuel pressure if lost for any reason, it is a backup, check Lyc manual for minimum acceptable fuel pressure.
Injected Maules use the Dukes for the above plus priming and/or flushing a hot vaporized fuel line.
