Model 2 Header tank, re: SB 29

[Mnflyer]

Hi Jacob, congrats on the purchase of your Kitfox, sorry to hear of the fuel problem. Glad to hear all turned out ok with the off field landing. Is the header tank you are asking about the round alum. one that mounted ahead of the inst. panel? or are you looking for one that mount behind the seat?

Good day to all- I have purchased my first aircraft, a Model 2, a bit over a week ago. Pre buy went great, ect, but on the maiden voyage back to the home airport about 50 miles away, we had engine troubles and we had to land the plane in a hay field with intermittent power. Come to find out, the previous owners never complied with SB 29. How this never happened over the TWENTY years and 400 hours of flight seems strange.

Now, come to find out, the fix for the problem is no longer available. Has anyone placed the new header tank on an older model, specifically the Model 2??

I want to fly my investment! J

Well, I suppose I am looking for the one that mounts behind the seat. I currently have the round aluminum one behind the firewall. As long as the repair fixes the fuel problem, I'm okay with it!

This issue has me confused.
I have a flying mod 1 and totally rebuilt it. I mounted the plastic
header tank behind the firewall to lesson the fuel lines inside the cabin.
The tank is vented back to both wing tanks and there has never been a fuel
problem with this setup.
I don't have SB 29
What was the problem that created the modification bulliton???

This is the original service letter

and the follow-up MANDATORY service bulletin which applies to all models prior to 12-08-1992 is here:

Hope this keeps you out of the hay field unless that's where you want to land.

One thing that comes to mind for this thread is using an early warning (low fuel) indicator at the header tank. I know Murle Williams has them here but I didn't see them on John's site (he may carry them). These come with a warning light that is easily installed on the panel...Gives you a little time to get the plane on the ground.
FWIW

I did have a problem
when the header tk was only vented to one tk.
It was not he header tk installation but on the tank not vented
to the header tk fuel line. Whih the wing in flight position the fuel line
was partially kinking, just enough to restrict flow.
The fuel burn was more than the flow and it got real quiet which
was nice but puckery. I opened the other tank and the noise came back
I put a small coil spring inside both fuel lines leaving the tank and the line cannot kink and no further problem. I got this idea from a skidoo 670, which had springs inside the fuel lines, also the oil lines.
