Fuel System
Always use appropriate containers to store fuel. It is advisable to install an anti bubble
system to the fuel supply circuit. The simplest one is a felt
filter clunk installed into the fuel tank. This helps maintain consistent fuel flow and greatly
reduces the possibility of air getting into the suction side of the pump circuit, which could
cause stoppages. To prevent the felt element sliding out of position a washer is fitted
between it and the feed tube – as seen.
A BVM UAT is another contemporary method of reducing the possibility of air bubbles in the
engine fuel line. This is a very important aspect of the operation of any turbine engine. Use a
appropriate adapter for the 6mm tube output of the UAT to the 4mm in the inlet side of the
fuel pump, direction of fuel flow is clearly shown at the top of the pump. The clear 4mm
tubing is used on the pressure side of the pump.
Clear tubing helps identify and locate any potential future problems with air leaks.
The fuel pump and ECU can be mounted simply with a pair of tie wraps and/or Velcro. The
best orientation for the fuel pump is vertical. It is important to ensure any fuel seepage
does not reach the motor brushes. The fuel feed from the pump to the engine should have
sufficient length of the clear tubing fitted to allow the fitment of the electronic fuel shutoff
valve and the valve should always go on the pressure side.
When making any fuel or gas line cuts use a sharp blade to make and cut squarely. The fuel
filter provided should be installed in an accessible place for regular inspection, close to the
intake port of the pump.
