912iS Fuel Pumps

by Craig Charters in General Tech Discussion 9 years ago

I have just received my new Bristell with a 912iS and I am unsure weather I should run the 2 electric fuel pumps whilst on cruse flight or only on take off and landing.
If someone could help me I would greatfully appreciate it.

Craig.

Run with both on. The Owners manual will be revised to state this.
The pumps will not wear out and it gives a safety factor and lessens pilot workload.

Thanks Rob
The fuel pressure in cruise is 45psi which seems high I thought it might be high because both pumps were on.
