New Kitfox owner

[Av8r3400]

How big is a highlander header tank compared to a Kitfox tank?

I thought theirs was a very small one, a piece of wing spar tube, like an Avid. I would think the larger Kitfox tank at a couple of gallons would be able to disperse enough heat...?

Kitfox headers are one gallon and believe it or not I think the highlander is 1.5. When I was looking at the UL, they recommended I increased my header to 3 gallons minimum or return to one of the wing tanks. This was due to vapour concerns. Hope this helps.

Taxied for about 20 mins today! Good news is that I don't seem to be getting any more oil past the turbo into the airbox. Best guess is that I had residual oil that accumulated over that 10 year sitting period and that once blown out and the motor run regularly it won't be a problem.

I still couldn't take the MAP past ambient air pressure and I don't think it is a fuel vaporization issue as it is a problem from the get go, not after running for a while. The previous owner flew for about 150 hours with the return line T'd right back to the fuel pumps on the engine side of the firewall. I don't like the setup of the fuel system and plan on changing it, but I haven't decided what I want to do yet.

Does anyone know what the factory is doing with the SLSA? I may need to take another trip to ID just to check out the airplane closer. At the time I did my training I didn't know enough about what I was looking at.

I think fixing my leaky carbs will make a big difference in my surging issue as right now anytime I go over ambient pressure I get fuel seeping from the fuel bowl.

Thanks to Paul for the heads up. I was aware of the vaporization issue but still am not sure how I want to proceed. How would one run the line back to a wing tank? Would I need to tap a new fitting in? Obviously the header tank would be way easier.
