    Normal rules do NOT apply here.
    This is like going to a homeless shelter. You eat what they serve. And you will enjoy it.

    Your imagination.
    For the O ring rebate/s (on the mounting bolts) you can use an end mill in your drill press. Use a slow speed for the dill press if you do.

    Yo, Sr. Way --

    Instead of o-rings & washers to seal the bolts, I've had really good luck using "seal washers" for this very exact same application ... by way of example, have a look at
    (Edit - damn, I'm having a hard time getting the URL to take you to the exact page but I'm working on it!)
    (Edit #2 - Well, hell! So far, all I've been able to do is come up with a URL that'll take you to a generic Mc-Carr page on sealing washers - my best suggestion is that you just do a search on Mc-Carr's website for "sealing washers". You're looking for a metal washer with a buna-n o-ring bonded to the ID of the metal washer [which does a good job of preventing distortion]. Some hydraulics-application folks are using these instead of crush washers - for example, Ohlins is using these on their X-Challenge shock reservoir hose banjo fittings now.)

    You'll, of course, want to get ones that'll fit your specific bolts/machine screws but McMaster-Carr's sure to have what you need. You just may need to do a little searching on their website but I know you can handle that. I used the Zinc-plated steel/Buna-N version and it's been flawless for the last 1.5 years.

    Also, if you can find it, some Permatex Ultra Rubber Gasket Sealant & Dressing #85409 can help your viton gasket to offset multiple sins of gasketing omission or commission. (If you can't find any, drop me a line and I'll send the tube I have to you as a loaner.)

    Cheers, John O

    Thanks John.....!!

    I looked at those but I thought (read) The Buna-N rubber was not full on gas proof..? I found these..... https://www.mcmaster.com/#viton-fluoroelastomer-rubber-washers/=19e00zj

    5mm....:-) I like the bears idea too.....:ilmostro

    Yeah, I had that same concern but hoped that having the elastomer trapped between the aluminum filler spigot base, the screw body and screw head (I think I used a hex-drive truss head screw, so wider screw head flange than normal), and the metal of the washer would compensate for any swelling and so help maintain the seal. Plus there wasn't a whole lotta $ at risk so I reckoned it was worth a try ... and it didn't need any special fabrications to use either. Best I can say is it's been working well so far but I'd guess that the washers wouldn't be re-useable.

    BTW, I used one of the filler bungs with the hose connection on the back. I cut off the hose connector then lapped the back side of the bung flange against 220 & 400 grit sandpaper to make it flat, drilled holes in the flange to match the BMW threaded backing ring, cut a viton gasket & used the Permatex rubber gasket goop, & screwed 'er together using the sealing washers. Absolutely no complaints so far and it's been well over a year in service.
