FWF,

but everything aft of the firewall.  I was planning on plumbing two RWS
electric pumps & filters in parallel, downstream of the fuel selector

valve.

The Lancair manual was written assuming I am doing a typical engine
installation and calls for a Cessna style gascolator.  I have two
questions, for those that are past this point.  1) Is a gascolator of

any

value when using a RWS EC-2 system?  2) Is a boost pump of any value
(upstream of the gascolator).  If you respond, an explanation of your
answer would be appreciated.

I see you are in Texas and your rules in the US might differ on this, but
you might might want to check. I'm about to start a flight test program on a
new Glastar with an NSI in it ( just waiting on the paper work ). The Soob
has two fuel pumps with much finer filters than a gascolator and the header
tank is the low point in the system and it has a water drain. On the final
inspection the only item that needed rectification was the installation of a
gascolator. The inspector said he understood that it was not nessecary but
it was in the regulations, if you could change the regs he would have no
problems without it. Of course the regs are as old as the junk the engine
manufacturers are selling. Interestingly enough the owner had no trouble
getting insurance, including hull right from the start.
