I have been checking Matthew Muckers list and the growth has stopped. He has put a lot of time and thought into making something useful because we asked for it.

In my opinion the wing tank option is the best.

It's not a bad bend but it's there and I want to know the best way to go about fixing it. I've submitted a phot to photo share.

I used a nibbler rather than snips to cut the hole when traversing from the top to the bottom of the trailing edge. This avoided any deformation that the snips would have induced when going around the bend... -- Best regards, Ray Montagne Cupertino, CA Zenith CH601-XL Builder #4939 ________________________________ Message 11 ____________________________________ Time: 03:53:08 PM PST US From: "Larry C. McFarland" Subject: Re: Zenith-List: Fuel center tank on 601hd --> Zenith-List message posted by: "Larry C. McFarland" Patrick, My old Luscombe had a tank behind the pilot and passenger and you had to look behind you to read a rolling gage. The difficulty of having a tank aft of the passenger on a 601 would be trying to balance a changing center of gravity during a trip. The Luscombe is a high-wing and this seemed easier to manage. What's certainly possible might not be a wise thing to do. Larry C.

My question: can these nipple elbows be repositioned (rotated) to correct my problem? I assume that I dont want to just grap them with plyers and rotate! Thanks Jon Green Bay, Wi www.joncroke.com ________________________________ Message 13 ____________________________________ Time: 06:02:41 PM PST US From: "Greg Ferris" Subject: Re: Zenith-List: 912 cooling elbow --> Zenith-List message posted by: "Greg Ferris" I had that problem too. Those fittings are threaded (pipe threads) into casting with a thread sealant. If you just rotate them, they will leak. Mine were stuck in hard enough that I had to ruin them to get them out (there's no hex or anything to get a wrench on, so I had to use pliers which chewed them up). I bought new ones and found that I couldn't get them in. The problem was dried thread sealant. I had to scrub at the threads of the casting with a brush and acetone to clean-out the threads. The other option is to remove the casting and send it to Lockwood. If you mark where you want the fittings positioned, they will remove the old ones and install new ones. This may not be too bad of an option when you figure the cost of the thread sealant and time involved.

Heat only the fittings! Dave > I had that problem too. Those fittings are threaded (pipe threads) into > casting with a thread sealant. If you just rotate them, they will leak. ________________________________ Message 15 ____________________________________ Time: 08:36:52 PM PST US From: Mike Fothergill Subject: Re: Zenith-List: 912 cooling elbow --> Zenith-List message posted by: Mike Fothergill Yes, they can. The threads are sealed with a heat sensitive threadlocker. make a wooden dowel that fits into the end of the elbows so that you can get a grip for rotaring it. gently heat up the threaded area with aheat gun or propane torch while applying some pressure to rotate the elbow. It will eventually rotate smoothly and reseal as it cools.
