Fuel primer line installation Carbon Cub EX

[PBY Catalina]

I cannot find those parts in my finish kit inventory. Are those parts, Sleeve/Nuts and the copper fuel line, included in the EX2 Kit or are they obtainable from CubCrafters?

Same question for me !

They were included in my EX2 kit. If I recall, the parts were in a misc. box., hard to find.

Installation was via the Firewall Forwrd kit.

I found it! Thank you Dan!


The routing isn’t very clear, but I should be fine.
Any picture or diagram showing the routing would be appreciated.

Might search here for some routing pictures as I recall finding some. Routing is pretty much 'what works'.

There is also option "B"; don't install the primer. I have mine disconnected for over a year now and no issues. One pump of the throttle before starting and the plane starts right up.

Never used the primer on my old C172 either.

I consider the primer lines a failure risk that I can negate by disconnecting the system.

Cheers and build on!

If the throttle pump is used while cranking, rather than before cranking, all the fuel is sucked into the engine. I have not used the primer in my PA-28 (O-360) for over 20 years.
