Kayser fuel filter. No crush washer

[Tones]

So got the kayser fuel filter from ecs. The crush washers it came with don't fit. Tried to reuse the stock sized one and is leaking like mad. Can't get through to ecs to ask about it. What's the deal Auth this filter. Teflon tape work? Gonna have to slap the old one on since I need the garage back.

I had to reuse my original crush washers. It stopped the leaking and should be fine. I would recommend changing them to the proper ones next time though.

Yeah I tried that. Mine isn't sealing with the orginal as it doesn't have any where to seat properly.


Edit. Lol. Now the crush washer won't seal with the old stock filter.

Crush washers are a one time use thing. You might get lucky and get a decent seal from a used one, but it's not something you should expect. Your best bet is probably to go to your nearest dealer and buy some (I'd recommend calling first to make sure they have them in stock). It won't cost more than a dollar or so.

Iirc, you don't use crush washers with one of them OES Keyser or oem mahler, just can't remember which one. They're also slightly different at the threaded end. I think the o-rings for the drain plug and the oil line (and vanos banjo) on the exhaust side of the head if you have any of those laying around.

You can steal the one from an oil filter kit, I did that when I encountered the same situation and was in a pinch

You know that is supposed to be true. I order all needed crush washers 90% of the time. But sometimes I miss one or two. I have never had those leak. not once...

Ended up filing a new washer inner diameter larger till it screwed onto the new kayser filter. Tightened it down with a skinny wrench and it's no longer leaking. That was a fun 3-4 hours.

Car is actually a bit faster that stock filter was pouring out brown. Wonder how dirty the injectors are.

I can't seem to find consistency in terms of who is really the OEM was for the fuel filters. I've seen both Mahle and Kayser in several different places - anyone know with certainty?

Also to follow up on the point above, the Mahle and Genuine BMW pictures on FCP's site shows the washer.

On my previous E46, when I went to change the fuel filter, the original one was still on there, as in, it was stamped 2002, and it was a Kayser.
Hope that helps.

Ya it's kayser and it doesn't use a copper crush washer, but you do use the copper crush washer with OEM Mahle filter.

Thank you both. I'll spend the extra $20 and grab the Genuine BMW since a non-Genuine Kayser isn't available from FCP.

Thanks again.

ECS carries Kayser fyi. But genuine bmw (kayser) from FCP probably worth it for future replacements.
