Pietenpol-List: Fuel tank question
Original Posted By: John Egan
Ken asks->Any suggestions on the set-up and hanging of the header tank in the piet?>Is most using two strap material, belting, or ?? If so, any photos of how>you are attaching the sides??The 16 gal. fuel tank in 41CC was fabricated with a curved top, sloped bottom,and "shoulder lugs" to allow it to sit on the longerons when in place. Additionally,it is supported by two felt-padded metal straps that pass underneath andmount to cross-members fore and aft. One of these cross-members broke at oneof the 3/16" holes where the strap was bolted through the wood, when the airplane'sgear collapsed and it went over on its nose. When I replaced the cross-memberI thought about changing the metal support straps with something likenylon tow strap because getting the metal straps to fit the tank right was takingsome fiddling around (nothing is perfectly square), but in the end I wentahead and replaced everything just the way Corky had it and it's that way now.Tow strap is intentionally made with some stretch to it and I didn't wantanything to get loose over time.I think if I were building from scratch I might see about using some seat-beltmaterial or something similar for the tank supports. Also, there is a metal strappassing over the top of the fuel tank than secures it in place.I have some pictures and will try to upload them to a webpage for you.Oscar ZunigaSan Antonio, TXmailto: taildrags(at)hotmail.comwebsite at http://www.flysquirrel.net________________________________________________________________________________Date: Mon, 25 Feb 2008 06:55:02 -0800 (PST)

OK; I put up a little webpage with a few pix of the fuel tank setup on 41CC. It'sat http://www.flysquirrel.net/piets/repair ... nk.htmlAnd I was wrong about the tank having 'shoulders' on the sides to rest on the longerons.What it actually has is a 'shoulder' on the aft side to rest on thecrossmember. Also provides additional fuel capacity. I have found (by experience;don't ask me how) that of the 16 gallons total fuel capacity in the tank,only 14 are usable. When that float rod touches the filler cap, I had betterbe on the ground or I'm flying a glider ;o)Oscar ZunigaAir Camper NX41CCSan Antonio, TXmailto: taildrags(at)hotmail.comwebsite at http://www.flysquirrel.net________________________________________________________________________________Date: Tue, 26 Feb 2008 11:51:50 -0800 (PST)
