To all Skyfox/Gazelle Owners!

I have now removed the two Fuel Non Return Valves from my Gazelle.

On draining both fuel tanks prior to removal of NRV's I could see that they were allowing fuel to backflow to the lowest level tank so clearly the "non return" function was not working.

On inspecting the simple internals I find that the flat fibre (?)disc has bent in the direction of flow - hence not sealing on backflow. The small fibre (?) sealing washer is also allowing a small amount of fuel to leak out.

Next job is to try and source replacements/parts?

The autoshop non return valves I bought on line (see earlier post) are not suitable - they need too much pressure to activate flow.
