Mysterious Engine Piece

The engine in my (new to me) Hilterhoeller 28 is a BMW D12. The device in the picture is mounted above the oil filter in the engine compartment. But, the black hoses coming to and from it are snipped and not attached to anything.

Can anyone help identify it and its purpose?

Re: Mysterious Engine Piece

That's a fuel filter.

Re: Mysterious Engine Piece

It looks more like a water trap than a fuel filter. Although water traps usually have transparent bowls.

Re: Mysterious Engine Piece

Not to date myself here but it looks to be a sediment bowl that was commonly used on most updraft carburetor engines made in the 50's. If you open the bowl you should find a small bronze filter inside.

Re: Mysterious Engine Piece

Updraft carbs - who in their right mind would have ever thought those things up? Make the engine suck up instead of down.

I suspect they were a British invention.

I, myself, personally intend to continue being outspoken and opinionated, intolerant of all fanatics, fools and ignoramuses, deeply suspicious of all those who have "found the answer" and on my bad days, downright rude.

Re: Mysterious Engine Piece

Harder to flood an engine with an updraft carbie.

Also assuming an inline engine it makes for a more compact unit.
