Header tank replacement

[airlina]

I am contemplating replacing my poly header tank in my Series 5 with the aluminum one that is sold by the factory, due to the persistent 100LL smell in my cockpit. Has anyone done this on their Series 5 or later model , and was it a remove and replace item or did you need to redo fuel lines because of tank size or port location differences. Thanks Bruce N199CL

Bruce,

I started with the poly tank, hated it, bought an aluminum one from John M....love the aluminum header tank.

I have an early series 7.....the aluminum tank was a direct replacement except that it doesn't stink or leak:D.....There is always a little diddling with the cushion clamps but the fitings, fuel lines, vent and sump drain all line up with placement of the the original poly tank.

Very happy with the aluminum header tank and would never, ever consider the poly tank now.

This sounds like a good idea though I solved most of my leak issues it still weeps ever so slightly.

Hey Bruce -

I've got the exact same issue, no leaks, no blue stains, but just the persistent
smell. Very annoying.

I use the blue lined fuel hose and no smell in the cabin.

I was wondering about the blue line..thanks Finn

Chase,
The stuff I used is not the semi transparent blue line but black fuel hose that has a blue lining (in case there was any confusion), think it is a Goodyear product. I get no fuel odors at all in my cockpit.

ok I am using the fuel line from spruce,,black with blue inner it's around $5 a foot? same stuff ?

Hey Finn, I plan on replacing my tank to header fuel lines with the new header , do you recall where you got the fuel line, Thanks bruce

[Dorsal]

Bruce,
The stuff I used is Goodyear 30R9 fuel injection hose (very low permeability). It was recommended on another thread like this and I have had good luck with it, found it at one of my local Auto parts stores. The stuff is not in the cheap isle :)

Chase,
Don't know if it is the same stuff that Spruce sells, what PN from Spruce?

As a data point I have the poly tank and stainless braided teflon fuel line. I think its teflon. I got it from Blue Sky aviation along with my turtledeck. Anyway, I have not noticed any fuel odor but I do have some mild blue staining around the tank fittings.

Finished replacing my old poly header with the new aluminum one from Kitfox, and it fixed the stink problem. I was hoping for a simple remove and replace, but alas this was not to be. Although all my fuel lines lined up fine, the mounting hard points were in a different spot on the new tank and my header tank drain didn't quite line up so some homebuilding was needed (read a 2 day job) Glad I did it though-no more stink!
