Configuration of that part of the fuel system which lies aft of the firewall will be very nearly the same the same for any Cruiser regardless of engine selection. Components to plumb the basic fuel to the firewall have been provided with the kit. However, some engine installations require a return flow provision which may require hardware not included with the basic kit.
Configuration forward of the firewall will be dependent upon the engine to be used plus many other factors. Therefore components to build that portion of the system must be defined and provided by the builder.
Before proceeding with work on the fuel system it might be a good plan to read the book "Firewall Forward" by Tony Bigeles, or a similar reference. These documents have countless techniques and ideas that can prevent disaster at a later time.
Fuel from each wing tank is carried by a short length of 3/8 I.D. neoprene hose to a bulkhead fitting at the side of the fuselage. A length of 3/8 O.D. aluminum tubing carries the fuel to each side of the selector valve and another tube then takes it forward to the bulkhead fitting on the firewall. The selector valve provided has a left tank, and a right tank position,, and off. Selectors with a "both" position are not recommended for low wing aircraft of this type.
After passing through the firewall the fuel goes via 3/8 aluminum tube to an electric boost pump and then to the gascolator. A flexible fire-resistant hose is suggested to carrythe fuel to the engine-driven fuel pump.
