Time for the fuel system. First of all I am making provisions for inverted fuel. I will be using the LH tank for the inverted fuel supply. The line exiting the fuselage for the LH tank has a 90 degree bend going forward to hook up to the re-located LH tank exit for inverted fuel. I am using an Imperial valve with three ports. The one in the kit comes with four where a plug is placed in the unused port. I am using the Bendix/Precision RSA-5 fuel injection servo and a Dukes boost pump. The RSA-5 does not need a return line, and the Dukes pump can be "fed through" for normal operations, therefore no need for plumbing around the boost pump. Lots less plumbing.
