Especially since you would really need two of them. It depends on
your fuel pump. If you use the diaphragm type, they already have a
check valve in them, if you use rotary ones then put a fuel pressure
regulator at the outlet of each pump--they are effective check
valves, or at least big flow restrictions when their associated pump
is off. You have the added benefit of a spare regulator and the
ability to change fuel pressure right from the cockpit for testing--
set one high and one low. even the good Holley regulators (the ones
that have a allen screw pressure adjustment) are reasonably priced--I
think about $30. You can even avoid plumbing a T is you get one dual
outlet one--just add a cross-connect pipe.
