Header tank filler neck

[Pilot78]

Has anyone replaced the filler neck on their header tank? The header tank on my F-19 was badly damaged in its crash. I have another header tank but the filler neck is damaged, thinking about having another neck welded on, some thing out of Aircraft spruce catalog possibly? If it doesn't work anyone got a tank for sale?

Yes, I did. The photo shows the aluminium weld-in screw fitting on my wing tanks (the same applied to my header tank). These were from Aircraft spruce (I can't recall the P/No).



I replaced all the other tank fittings with weld-in threaded fittings as well:

Next photo shows the header tank with the steel filler neck screwed in. It does make them more proud than the original, but that's not a problem to me.

Re: Header tank filler neck

Years ago I had to do some engine work. After the engine and mount was removed I decided to remove the boot. The filler neck was held in place with several screws through a flange. At this stage I thought this was normal. As the last screw was removed there was a loud noise of something hitting the bottom of the tank. With the filler removed I could see where the filler neck had been removed by using a saw. A flange was fabricated and welded to the filler neck. Now the retaining plate was in the bottom of the tank. With a magnet I got the plate to the opening. That is when I asked myself how did they get the plate through a hole smaller than the plate. There was a slot in the plate so it could be sprialed to the inside.
The flange and retainer plate were drilled and the inside plate tapped. Using a threaded rod the plate can be held held in place while the gasket and filler neck are threaded into place and the screws installed.
The IA that maintained this airplane before I aquired it was very clever mechanic and a outstanding fabric man. I am sorry to say he has been gone several years and that expertise is gone forever.

Most of the tanks are Tern plate, cant weld it, it must be soldered. A good radiator shop can fix this easily. Tim

Not in an F19 they weren't!
