I doubt that the gascolator is designed for 40-90 psi. If not, it needs
to stay before the high pressure pumps. Instead of check valves, put
filters after the pumps. My understanding is the gascolator keeps big
stuff out of the pumps, and filters afterwards keeps pieces of the pump
out of the injectors should it deteoriate plus any smaller particles
that get thru the gascolator.

If a gascolator won't take 50 psi don't use it as the pumps
may not prime sucking through a gascolator.
There is no gascolater in the Lancair designed system before
the high pressure pump. Here is the schematic again.
As Mark Wrathal says "pumps blow they don't suck".

We are seeing problems with some of these Common rail diesel powered
aircraft in Europe with a HP pump well down stream from the tank. If a
suction line leaks, fuel doesn't leak out, air is ingested, and it takes
very little air to stop a common rail diesel engine.
