Talk to Kinsler Fuel Injection  (1-248-362-1145).  They have two different
style check valves (and fittings for same), which can be used expressly for
this purpose .  The first is a "flapper" style check, which has the
advantages of a very low cracking pressure and good flow potential.  The
second is of the "spring loaded poppet" style, which offers more positive
sealing while imposing a relatively high cracking pressure.

If purchasing industrial hydraulic equivalents (Parker, etc...), be mindful
of the overall flow potential and pressure drop issues.   They  can tend to
be somewhat constricted internally, despite the appearance of large
entry/exit ports.
