Installing a UL350is in a Cruzer and am pondering a header tank. There seems to be a lot of good reasons to have one a only a few not to. The possibility of voiding a fuel line during uncoordinated flight is not a worry with a header tank. A duplex fuel valve is not required. A header tank adds a bit to the expense and has a couple of gallons of fuel in the fuselage.
I would appreciate hearing from anybody with some experience and advice with this method.
Sorry, we're using the Viking 2.5 gallon header tank with two installed fuel pumps. Also has a low point sample/drain on the bottom of the header tank.
Ken - you seem to be smart on this header tank issue, and I honestly am not. Not at all. I've already riveted my two 750 tanks in, and I have the two aft fuel lines in place, and I have a standard 912 ULS, and NOT fuel injected, and my tech counselor is telling me I need a header tank - for many of the reasons you list above. It all makes sense, but I'm clueless as to what to do next. I have no idea what to buy, where to mount it, how to install it or anything. Would you mind if I gave you a call? If you have a problem with listing your number here, I can put mine, so you could call at your convenience. I'm on Central time, and 334-717-6873. I promise not to take much of your time, I just hope to get some idea of how to move forward. Or if there's anyone else smart on header tank ideas/installation for Rotax ULS 912 gravity feed, I would welcome a call as well. I'm stuck! I have seen the homebuilt videos. Thanks,
Hi Bert, I too am not real smart on header tanks. However, I can not for the life of me see any significant advantage of having a header tank for a high wing, gravity fed, carbureted engine. And surely not for the extra work expense and additional parts to fail. IMHO
Perhaps someone will enlighten me! :-)
Pleasure talking to you Bert. Email is on the way. --Ken
I also built and fly a CH 750. It is the first addition completed in 2011, Rotax 912ULS; about 400 hr. The plane has no header tank, only one fuel supply from each tank, per plans. I fly the plane in all kinds of attitudes, steep turns, descents ,slips, etc, without any engine problems at all. I would leave it out, save $ , save weight, save space, and safer with out extra fuel connections and fuel close by. My two cents worth.
I see you have a UL 350 IS, that's nice.
