Rotax 582 fuel flow sender
in 2 Stroke Technical Questions
10 years ago
Looking to install a fuel flow sender on my 582 aircraft. Two options, one is a low pressure differential after the fuel filter on the suction side of the fuel pump, the other is to join the two separate fuel lines after the pump, install the sender and split them againafter the sender to the carbs.
Rotax have said that the latter option is ok, by email, but I am uncertain. Does the diaphragm fuel pump actually pump on the the same cycle to both outlets. I wouldn't want one outlet to 'suck' and the other to 'blow' and cancel each other out. Begs the question why rotax set up two outlets on the pump. I suppose if the diaphragm in the pump got a hole/stopped working both carbs would not get a supply, maybe the two outlets are for convenience and simplify fuel plumbing?
Anyone installed a fuel flow sender on a 582? If so where. No I don't use, not want to use an electric pump.
Thanks
