Get a used fuel pump from an older VW CFI (constant fuel injection) auto
--they put up 70 psi constantly---ought to last a long time pumpin oil--
just draw up high enough to not get any of the settlin's outa the sump.--
the older ones were frame mounted just ahead of the gas tank in a big
rubber jacket--about 4"x4"x8"---or you could just put quick disconnect
fittings on the plane & leave the pump in the hangar. (that's what I did
with my 855 Cummins.

The accumulator method is heavier than I want to use.
