fuel bowl needle valve - how to de-magnetize

[Andrew Vanis]

I noticed that the needle valve in the float bowl is magnetic and attracts metal shavings. How would I de-magnetize it?

I'm guessing a magnetized needle valve is a bad thing since it would collect any metallic bits from the fuel tank wearing the needle and the seat and since the fuel volume/pressure is not that great (I'm guessing) through there, those metal shavings won't get flushed into and settle at the bottom of the bowl.

How did you manage to magnetize it in the first place?

I gotta say, that is a new one on me. Google "How to demagnatize metal". Lots of choices, some good, some not so good.

With a degaussing coil.

You can wrap an AC power cord around whatever you are trying to deguass and use it for a degaussing tool. Use the cord from something something that pulls some current. Plug it in, can't remember how long it takes, haven't done it in thirty years.
No clue if it will work on something as small as this valve.
Heat can also get rid of magnetism, but I don't know how hot it would take or if the needle can take the heat.

I wouldn't have thought they are even ferrous, is this the stock needle valve?

Tom...My impression was that he means the float needle, which is ferrous metal.

De-magnetise

Years ago I used to demagnetise the pick-up heads on cassette players with a demagnetiser pluged into the mains. Perhaps that could work. I think I still have it, may have a makers mark that could help. Dennis
