My reason for the pumps in the wingroot centers around the Fuel selector valve in the cabin. The valve (per the plans) winds up about 12 inches (give or take) and is most certainly the high spot in the fuel system I was (and still am) concerned that low fuel levels in the tanks would lead to a low enough head pressure to not get usable fuel past the valve.

I have plumbed my fuel system entirely with aluminum tubing thus far and will do so to the firewall. The only flexible line is from the firewall to the engine and that is the braided line like the one pictured in Ron's post. Rubber fuel Lines: If the rubber fuel line was supplied with the pump and the pump was purchased from an automotive parts supplier, it is safe to assume that the lines are for that application and therefore probably will not be affected by the ethanol. Any fuel line purchased for the automotive application should be ethanol safe. Hose clamps: Standard practice in the Marine Industry is to double clamp all hose fittings below the waterline for safety. Obviously that would increase weight in the aircraft application and that would be undesirable. There are always spring clamps available. Spring clamps are very common in fuel systems and you can get the clamps at any auto parts store. AN fittings are in my opinion the best way to go with either hose or tubing. Fuel pump Placement: Fuel pumps are designed to provide pressure, not draw a vacuum. Obviously they will draw some vacuum but this is not their intended purpose nor their strong suite. The fuel pumps should be placed as low in the system as possible but not lower than the gascolator. They should be placed after the Gascolator to avoid as much debris going through the pump as possible. Pre-pump filters are common on many fuel systems. As long as the pumps are below the tanks outlet and are gravity fed they will pump. I would prefer the pumps be as close to the engine as possible. I think the firewall is the best place for them. That being said, the pumps are sufficiently strong to supply the pressure as far away as the wing roots. So I think that option should work as well. -------- Brady McCormick Poulsbo, WA www.magnificentmachine.com Read this topic online here: http://forums.matronics.com/viewtopic.php?p=221379#221379 ________________________________ Message 10 ____________________________________ Time: 11:39:40 AM PST US From: "Roger & Lina Hill" Subject: RE: Zenith-List: Fuel lines MY fuel wing tank selector lever on the 601HDS is actually on the floor between the seats.

All I need to do is to carry it to the garage, attach the wing tip (it is very hard to go up the basement stairs with it - lesson learned when the right wing was moved) and place it on a shelf built for that purpose. So I thought some planning was in order: I visited a few web sites and stared at a number of pictures of CH601-HD(S) centre wings, refreshed my memory on the different components, etc. So far so good. Then a mandatory stop at Larry C. McFarland's web site - and a cold shower. Larry's building narrative is covered in journal sections 1 through 7. He was done with the wings by the end of section 2, and was already working on the fuselage. If the relation holds, I need another 25 years to finish my plane... Sigh...

From: jaybannist@cs.com Anthony. My flap skins were not pre-drilled, so I just offset the holes enough to allow both rivets to be set.? If yours are pre-drilled, the best answer is to find some Avex rivets that are long enough to clinch the joint, but short enough to eliminate interference.? You might also try inserting rivets through both sides at angles to each other and then pulling them a little at a time, alternating between rivets. You are going to find, later in the construction, other places where interferences occur.? This is especially true where you install A5 rivets in both legs of an angle.? With the tail of an A5 rivet protruding toward the inside of an angle, there is no way you can get clearance for the rivet gun to pull a rivet from the inside of the angle. In one instance (on the firewall, I think), I hadn't offset the holes and had to drill out a whole row of rivets. When I re-did it,? I set the rivets in the first leg from the inside of the angle (head inside, tail outside), those in the other leg I set from the outside of the angle (head outside, tail inside).? Moral:?

Zenith will tell you to cock them crooked and while pushing down and pulling with a hand puller straighten them up as you go. That didn't work for me so I drove the center stem out and ground the body short enough to fit put the pin back in and pulled them -worked good- but would do it only with that last rivet on trailing edge because they won't be as strong. David Coberly 601XL / Corvair ________________________________ Message 18 ____________________________________ Time: 01:48:27 PM PST US From: Terry Phillips Subject: Re: Zenith-List: Re: Flap Trailing Edge Rivet HELP! Anthony Don't drill. FWIW, I'll append my comment from my builders log regarding this problem. It must have worked, because the rivets are in place now. "3. After the bottom was riveted, the trailing edge rivets could not be inserted on the top because the rivet on the bottom is in the way. The pilot holes should have been offset to avoid this problem. I recall there was a place on the empennage where the holes were offset to avoid this sort of problem. ZAC really should modify their pilot drilled kits to eliminate this conflict. 4. Called ZAC; Caleb suggested tilting the top rivet and forcing it in until an edge was in contact with the skin. Then pulling the rivet with a hand riveter and moving it normal to the surface as it shortens. He said that if the rivet could not be inserted until an edge was in contact with the skin, then the hole should be enlarged with a drill at an angle until the rivet could be inserted. After examining the aileron skins for the same problem and looking again at the flaps, I concluded that the conflict would be reduced if I had riveted the top- trailing-edge-skin before the bottom skin. It looks like, because of the angles and placement of the pilot holes, a set bottom rivet interferes with the top rivet insertion more than vice-versa." Good luck.

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

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..
