Posted: Fri Sep 18, 2009 6:36 pm Post subject: Cabin fuel lines

I'm wondering what might be the best way to run fuel lines through the cabin. The plans don't specify material but Zenith supplies rubber hose with the kit. Would a solid material be better? Rubber should be ok as long as it is changed for new every so often. Aluminum or steel can crack from vibration. Rubber cad dry-rot and is easily cut.

I want an easy way to disconnect the fuel line at the side skin in order to remove the wing. What about fittings? there are many types to choose from. How do I get through the firewall? Does anyone know where I can get a good explanation of all this?

I used 3/8" OD 3003 aluminum tubing from the tanks to the fuel valves.  

It's easy to remove the wings by just unscrewing the flare fittings  

and sliding the tubing out through the grommets. There's no  

significant vibration in this area, so it should last a long time. I  

used the supplied rubber lines for the rest of the system because it  

is relatively easy to access for replacement. At some point, I may  

replace much of this with aluminum tubing also. The only place where  

vibration is a concern is between the firewall and the engine.  

Flexible hose is required here.

I am a firm believer in using only the same grade of parts for fuel 

lines as a normal "certified/production" aircraft would use. I have used 

all metal tubing and factory made flexible hose with AN fittings for the 

fuel lines. The pictures are posted on:

Chuck-

    I used 3003 in the cockpit through my C-section, flexible from the 

header to the firewall-through, and flexible to my carb. The odd fittings 

you need to go from the C-section to the wings aren't available from ACS or 

Wicks, the place I found them was Murdoch Industrial. I realize there are 

differences between the 650 and the HDS, but my main point is, the odd 

fittings you'll need are available from Murdoch.

                                                                             

        Bill

Thanks to everyone for the advice. 

I,m not sure what factory grade fuel lines means. Is it 3003 aluminum or something else?

There are too many different fittings and materials.

The car guys have similar problems. They use aluminum some times but generally don't recommend it.

Should I use a single flair or a double?

I flaired some aluminum for practice and it seems like it might be fine but I'm not sure. 

How about 3/8 aluminum jic 37 degree fittings with single flair stainless steel lines.  Hard to get the seat to seal but they make soft aluminum sealing washer for this.

Get an AC43.13. It has all the info on materials and fittings for fuel systems and is considered FAA approved data.
