All-

     With the HD/HDS you have no  choice but to use some of the rubber fuel line. If not, you'd have a hell of a  time getting the wings on and off. Also, you will be under pressure (Suction,  actually) in the cabin for a short period of time while you fill the header from  aux tanks. No problems reported from either Larry Mac or Jeff  Small.

     As far as ethanol is concerned,  I'd be more worried about it dissolving the carb gaskets than the fuel  line. Someone mentioned an alcohol testing kit. Testing might be a necessary  addtion to your preflight procedure in this day and age.

     Reports from HD/HDS people with  headers encouraged.

                                                        do not  archive

MY fuel wing tank selector lever on the 601HDS is actually on the floor between the seats. I actually stepped on it once and broke the line up to the main tank. Then when I switched on the transfer pump it pumped fuel all over the cabin floor (fortunately, I was still on the ground)  Important safety tip, until your fuel system is proofed out, don’t install carpet or anything that might hold fuel after a leak into the cabin….

Hi Bill,

After speaking with Bing folks, I discovered they have reformulated 

their floats, gaskets and such same as VDO gaskets on senders

about 5 years ago.

Larry-

    I have a $1000 MA3-SPA rebuild, and I don't want to jeopardize the 

integrity.

    Bouncing back and forth between converting my antenna to HD-TV (Worked 

great- I get 15 channels for free- cost me $175 and killed the day for my 

son and me) and assembling a family photo montage for my aunt and uncle. I 

have to go to Wal Mart tomorrow to have some daguerreotypes  turned digital 

so I can finish up. These of course are from my, my brother, and my cousins 

early years.

    I really want to get my uncle to sit down for an EAA "Living legends" 

session. My son has agreed to act as cameraman and I'll hit him up when I 

deliver the photo montage. He has a phenomenal and atypical story.

    If things go right, I'll actually get back to work on the project 

Monday.

    You have to agree, you can't get the wings on and off with hard tubing.

Roger-

     Mine is too. I'm not quite ready  to get in and out of the cabin yet, so this could be a real  problem.

                                                                     Bill

You're correct Bill, I've got braided line from the center section ends 

to entry into the cockpit.

That only affords a slightly flexible disconnect should that ever be 

necessary.

Larry-

    I was planning on using the Zenith supplied hose from my locker tanks to 

spade fittings at the outboard/c-section juncture. Cockpit runs are hard 

aluminum to the console Facet, Zenith rubber tubing to the top of the 

header, then braided to the firewall-through fitting. The only possible weak 

link is from the console Facet to the top of the header.

    We are fortunate in this area in that fuel for the two largest gasoline 

dealers is refined locally. I used to work right behind the refinery and can 

easily find out if any ethanol is added. This should save testing every time 

I fill up.

                                                                             

            Bill

all

i have Stainless Steel braided teflon lined fuel lines from the tanks to the wing root with AN fittings just inside the cabin.. then aluminum all the way thru the firewall. i too have the tank selector at the top of the center console. i calibrated the gauges several times by temporarily hooking up a 12 v. Chevy elec. fuel pump on the outside of the firewall. i pumped both tanks down to about a quart of fuel every time and i was pumping way faster than the Aircraft set up. it never missed a beat. you could tell immediately by the sound when the pump started to cavitate.  at that time the tank was empty except for the quart or less that could be drained from the sump. 

hope this helps.

Do you have a picture? Or better yet hose/line lengths?
