Michel,
I have check valves on both sides next to the tanks. So the valve on the opposite
tank stops the flow if the selector valve leaks a little. The selector valve
only allows flow from one side or the other at any one time as long as it
is fully in the detent. My Facet pumps are operated independently, usually one
at a time as intended. There is documentation that the Facet pumps do allow
fuel flow in the backwards direction when not operating. If anything, the check
valves are overkill but Chris himself drew it up for me. And Fred Hulen,
or was it Hinde, anyway the fluid design engineer on this list agreed. Anyway,
it seems to work for me.
Jeff

be much more back flow into the opposite tank with a check valve than without...
So i decided to deinstall them.
