Kitfox w/912 - fuel hoses too short

[AlbertaPilot 5]

Hi everyone,

I'm in the process of upgrading my Kitfox Model IV from the 80HP 912 to the 100HP model.

I just picked up a brand new 912ULS earlier this week. The problem I am having is that the new 912's come with factory made fuel hoses with banjo fittings on the ends, and because the engine mount configuration on the Model IV's require me to swap the intake manifold from the left side to the right, that carbs are now farther apart and the fuel hoses are too short.

One option is for me to use the old fuel pump and carbs from my 80HP engine, but it would be a shame not to use the new carbs that came with the new engine.

Another option would be for me to use the new carbs but mount them with the throttle linkages inboard, if I did this the fuel hoses would probably reach. I don't like this idea though because it would make inspecting the throttle linkages and syncing the carbs more difficult.

The best option in my mind would be to fabricate a new fuel hose assembly similar to the one supplied by the factory, but with longer hoses. In order to do this, I either need to find a source for the banjo fittings at the carb connection, or find a hose barb fitting that threads into the carb instead of the banjo bolt.

Have any of you guys ran into this issue? If so what did you do to solve it?
I've attached photos of the factory supplied fuel hose assembly that I need to extend.

Thanks in advance for your suggestions.

Hi Randy,

 

I don't know what your best option would be, but you might check with this company:

 

https://www.tsflightlines.com/

 

They have an excellent reputation with the RV crowd, and they make lots of lines for the RV-12 which also has the 912. They should be able to fix you up if you decide to do new lines.

I thought I saw that Rotax has those fittings available direct... ?

Next I would try the local NAPA or hydraulics shop to see if they can make a system up for you.

Thanks guys, I did find the banjo fittings in the Rotax parts catalog so I will order a couple of those and fabricate some new lines. It does look like the guys at TS flight lines do nice work though.
