can anyone help me with a few questions?
im putting a 914 in a 701 .
where is the best spot for fuel pumps?
where in line should the fuel shut off be located?
where can I get the one way check valves rotax wants?
do you install one pump to run all the time and the other to be a switched bost pump?
does everyone have the wastegate servo override switch installed in the panel ?
thanks

========
Tracy, I think that you want both electric fuel pumps to be controlled with switches. My Sky Arrow has the main pump switched with a guarded switch; which of course runs all of the time unless I want to check the output fuel
pressure of the backup boost pump on the ground by turning off the main pump.
