The problem thar could hapen with the quick disconectors  is that they use a seal (o ring or something)  and in certain ocasions some car gasolines will damage the seals...   

  When removing the wing I think is better to complete drain the fuel remaining in the tanks.  then remove the hose with the clamp.   I think is  a safer way all around.

easy wing removal and reattachment but wing tank are safer. Im uneasy to the 

idea of a gasoline tank over my feet. You can get wing tanks and do away 

with the header tank on any of the 601 models.

Some of you probably can answer this,



What do FAA types and DARs think about the idea of connecting wing tank fuel 

lines to the fuselage lines/valve using quick disconnect couplings? They 

have the handy feature of shutting off fuel flow/dripping from both sides of 

the coupling when they are disconnected. At $26.00 per set they are pricey 

but it's worth it to not have fuel running all over the place during 

disassembly or service. I use them on my UL but have never asked if they are 

considered safe enough for the more complex experimental aircraft.

Yes and I have to point out that in 6.5 years and 400 hourse I have

never taken my wings off and that includes for when I made new wing

splice plates (per ZAC's AD) and pulled out a leading edge wing fuel

tank.

I don't think quick disconnect is required (I believe

one of my friends had problems with quick disconnect

and auto fuel...).  I use a simple AN fitting to

attach the short rubber hose from my tank to the fuel

pump.

Not very clear on the picture, but there is a short

section of aluminum tubing that loops under the pump

(fixed to the rib). The tank fuel hose connects with

this tube.  It can be detatched within seconds.

I have used the quick disconnects available from Aircraft Spruce for over two years on the ultralight (50:1 87 octane and 2-cycle oil) without any leakage or detectable deterioration of the O-ring seals. My concern was in regard to the acceptance of their use by the FAA. In practice, I have found them durable and dependable.

The fuel system was one area that I demanded heavy-duty hardware.  I

wanted a system that I believed could withstand some abuse.



As a result, I am strictly using only steel-braided lines and -6

fittings.  You can even use the standard ZAC fuel system parts - you just

have to use a -6 to 1/4" pipe fitting.  While I will admit, they cost

significantly more that standard rubber hoses and screw-type clamps, and

yes, they are much harder to work with, but to quote William Wynne on the

subject "If you ever put your plane down in a field, the last thing you

want to do while you're trying to climb out of the cockpit is to smell

fuel".  I can assure you it would take something pretty extraordinary

to rupture these lines.

Hmmm....I think the something extraordinary is having the fuel tanks

punctured as the wings get ripped off!



I don't honestly think the choice of fuel line will make much

difference. Having a firesleeve on the fuel lines under the hood is

probably a good idea though.



Just my humble opinion.

Just replace the o rings with VITRON or VITON,     how ever you  spell it.

Thanks a lot Ed,   

   

  This first hands on comments and experience is what we all need to hear when talking about something we are going to use for flying.     

  I have several bad experience with hoses and some "O" rings  in my vehicles (cars, motorcycles and ultralights)  that I first have to be sure they work with the gasoline available here before using them...

Yes Bob,

   

  I always use Viton type of O rings, but some probably are not "pure and virgin" and they fail,  at least get bigger and wont fit once they spend some time in the fuel...   

   

  Now we know the Quick Disconects work,  next time I order something from Spruce, will buy 2 or 3 sets,  just in case I find some use for them.

It's either Viton material or it's not,,,nothing in between.  Bob U.
