Paul,
Why use a gasolator if you have a sump tank with the outlet a = couple=20 inches off the bottom of the sump? Won't the sump tank catch the water = and a=20 strainer stop the big stuff. The sump is checked before each flight = and a=20 gasolator isn't. Go straight to the FP then thru a fuel filter and = then the=20 fuel rail. Eliminates the restriction, weight and connections to = leak. I=20 am beginning to lean towards in-tank pumps with built in = strainer since=20 all this has come to light.

Hi, Kelly....the efi pumps are the = last item=20 before the fuel rail and fuel pressure regulator. Here is the basic=20 system...  The fuel in the main tanks goes downhill to the fuel = selector. Fuel then goes downhill again through the Facet pump into = the top=20 of the sump tank. Fuel then comes out of the bottom of the sump tank = through=20 the gascolator into the EFI pump(s), then to the fuel rail with fuel = pressure regulator attached, then that returned fuel goes back into = the top=20 of the sump tank.  That is the complete system. Take care. Paul = Conner
