Belly Tanks Fuel

This blog covers the construction of the fuel delivery system for the belly tanks.

Overview
With both belly tanks fitted to the hardpoints a means of supplying fuel to the main tanks is required. In operation any given tank is run down to about 50% then the opposite side tank is selected and the fuel transfer pump turned on, fuel is then delivered to the tanks using the existing fuel return line.

Installation
Aeroflow fittings were used to construct the piping in conjunction with short loops of 3/8'' rubber fuel hose to allow flexibility in service and at installation. Two check valves are incorporated to prevent fuel traveling in an untended direction.





At the the hard points [rib #9] more aeroflow fitting in conjunction with a dry break valve. allowing the fuel line to be broken and re-connected without fuel spillage.





Two plug provide power for a fuel pump located in the belly tank along with a second to connect a Belight low fuel indicator to be incorporated into the tank. The tanks are yet to be offered by the factory but now is the time to install enough hardware to meet the future need.

Comment
These fittings are not cheap but they are a solution in a box and I am short on time.
