I have pondered and procrastinated for several months on the ideal location for a gascolator. I had even considered not putting one on at all. Knowing that this relatively heavy chunk would be the last-ditch defense against universal water intrusion, it had to be low-point in the fuel system for any possible nasty water to flow downhill to that sump. Problem is: my KR-2 carries fuel (and water) in the wings. The bottom of the inboard end of the outer wing and corner of the fuel tanks are the low points on each side. Those are the absolute low points in the fuel system. The only possible location to get the gascolator lower than that, would be to hang it out in the airstream on the belly. (Can you see where many years of high-wing Cessna 150 sumping have fogged my logic processes?) In a shining moment of inspiration (by Tony Bingelis) I realized that it did not matter. The real consideration was for the gascolator to be the low point before any fuel was allowed to get to my VW 2180 carburetor. And there must not be any low points in the system to trap water without draining to a sump point such as the gascolator or fuel tanks. Since my carb is mounted relatively high on the back of the engine, I have lots of vertical latitude to bolt the gascolator to the firewall and route a fuel line through the firewall to avoid rudder pedals, cables and load bearing structure. I have installed a Cessna style quick drain in the gascolator and fuel plumbing is proceeding.
