Also is less prone to cracking next to a weld they say.

Cold Rolled Electric Welded tube is normally made from soft steel, usually 1018. 4130 is what they call aircraft tubing. It is made in a similar manner but out of a completely different material. Never substitute the two. Well you could sub 4130 for 1018 but not the other way.

Cut that aluminum tube to fit your sender unit but cut the cap 1-1/2" larger in diameter, weld the the cap centered on the tube and cut a hole in the top of the tank so the unit will fit. Use a fly cutter to make a reinforcement ring for the inside of the tank, install platenuts and flush rivet to the skin. Using a cork gasket or other shaped gasket sutitable for the tank, proseal the bottom side of the cap lip.and attach with # 6 or 8 flathead SS screws. When riveting the reinforcement ring into place be sure to use capped rivets. There are more steps involved including match driling the cap skin and ring together before installing attachment hardwear, but I assume you kno how to do that. Installation would be similar to installing the gas cap assembly. if you can build it to match the curve of the tanks section, you will have a removable unit that just looks like and inspection hatch. From there you can get fancy. Also keep in mind that adding changes that deviate from the plans will add substantially to the time it will take to get your plane into the air. The downside to this arrangement is the wiring inside the tank, so don't forget retaining clips of better yet an aluminum tube to run the wire to the unit. a heavier walled tube could be threaded and installed in the end of the tank using a nut and proseal on the inside and a gasket, washer, proseal, and locknut on the outside, After the wire is in place fill both ends of the tube with proseal. Just a suggestion, seek the advise of Zenith before making these or any other substantial change to your aircraft.

My reasons for this are twofold; the first one is if it leaks I won't lose a half of tank of fuel,and secondly, the sensor will be replaceable without having to tear the wing apart to remove the fuel tank. As for the clearance problem, I am going to rivet on a slightly domed circular access cover. I have already modified the sending unit and it just barely will clear but I feel the domed cover will be a bit of extra insurance. Has anyone run across a domed cover like this anywhere?

(By the way, the suggestions floating around modifying the fuel tank itself are good ones, but unfortunately I'm beyond that point). I've looked everywhere for some sort of domed cap with a flange so that the cap can be riveted, but so far I haven't found anything. I tried to make one using a wood block form and a ball peen hammer, but that didn't work well at all. Looking forward to hearing some great ideas!

I'm new to the list; and, new to building. I've purchased an "almost completed" 701. Here's my problem: I leveled both fuselages; but, after drilling and clecoing per the plans, I noticed on the right side the front is a little low. I don't know how I got off; but, it is. Now, the question: How do I fix it; or, does it need fixing? I can pull up the front tube to get it level; but then the tube is not resting on the "L" angle on the side. Help! I'm not doing anything else until I hear from experienced builders. Jim
