SR fuel system questions
Posted: Sat Feb 18, 2012 9:05 am
After reviewing the archives for fuel system ideas, my plan is to keep the fuel system simple. The fuel lines will come in from the wing tanks to the fuel shutoff valves, then run down the rear door posts and tee together under the floor. Then into the gascolator at low point and then into a header tank (fuel injected engine). Gascolator and header will be under the floor. Output of the header is to dual electric fuel pumps. No fuel selector switch to manage so as long as there is fuel in either wing tank there shouldn't be any chance of fuel starvation. I'll use the 3/8" supplied aluminum tubing supplied by MAM.
Any recommendations for gascolator model? ACS has models for less than $70, including an inexpensive "homebuilder's special" but it is not for use with auto fuel. Andair and other gascolators are much more expensive, $150 and more. Is this a case were it's worth spending the extra money?
How big does the header tank have to be, 1-2 gallons? Where can I get a header tank this size, or is it easier just to make one? I'll vent the tank back to the overhead cross vent line, routing the header vent line back up the rear door post. Can I get by with 1/4" aluminum tubing for the header vent or should I stick with the 3/8" tubing?
