Facet Pump recommendation 912S

The choice is mostly up to you.

With a high-wing A/C you will not need more than 4 psi and a check valve will not be needed but also will not hurt.

Install it below the fuel tanks in a cool location, preferably not in the engine compartment; But if you must, mount it as low as possible.

It is a good idea to operate the pump whenever below pattern altitude or if you even suspect a vapor lock condition.

Vance,

It will work fine, that’s the pump I am using in my 701. Following the diagram in the Operator’s Manual, I installed it downstream of a fine filter on the fwd fuselage floor with a bypass circuit should the pump fail in a manner that blocks the fuel flow. Echoing Bill’s advice and per the manual I’ve got a one-way check valve in the bypass circuit. Personally I consider a fuel pressure gauge a required item, and I fly with the electric pump operating for every takeoff and landing.
