Re: Model IV 912 fuel line
Did a little disassembly last night, and found that the block that I thought did something great with the balance tube doesn't actually do anything with it. All the screws and caps are access to the same fuel line. So it is just a manifold for the fuel lines. And, the port on the balance tube must just be where you'd plug in a MP gauge if you were using a flight-adjustable prop. Doesn't really change the questions. I'd still like to know if it would be better to try to keep the balance tube with the port and the fuel manifold.
Re: Model IV 912 fuel line
Where do you buy fuel hose fittings for the inlets to the Bing carbs? Is there a banjo-to-barb fitting that is used, or do you just use a straight NPT-to-barb fitting? What is the thread in the carb?

Try L.E.A.F. or California Power Systems. Both are sponsors of Teamkitfox.com and have adverts on top of every page. Both are Rotax dealers and have all these parts. Which ones you need may be related to the age of your engine.
