Hello,
I haven't seen this grommet available on Mark's site. Does anyone know if is available or will I need to replace the entire unit?
Thanks,

I assume you're talking about the boot at the taco plate for the oil pressure sender at the center of your flashlight beam?

AFAIK nobody is making them as repros yet, but you might find a better used one on here.

You might try finding a close match in a similar 911/912 or 411/412 VW OP sender which might fit.

Check in an old Parts Exchange Catalog for VW & Porsche - if you can find one, to see if any are an exact match to widen your options in both used & new/NOS..

Also, I know some folks have had luck with some of those home DIY rubber molding kits, but I can't speak to that for making a one-off repro part.

Hopefully 3d printing will make such repro parts in flexible rubber - as well as other NLA parts in many other materials - in the near future.

PS - As a temp fix you could also remove that boot, clean the grease off of it completely, then use some silicone or other rubber adhesive (e.g.: Permatex rubber window gasket adhesive, etc. from the FLAPS - try to get oil resistant type) to repair the old one from the inside - perhaps using some black cloth electrical tape or nylon mesh as a strengthening patch on the inside surface for any tears - adhesive-screen~embedded-adhesive - to hold you over. Let it cure completely for 2-400% of the normal cure time before trying to reinstall, so it's as sturdy as possible before any stretching & working it over the wires/connectors & the boot over the taco plate flange. It may not look perfect, but it should seal the connectors off for now.

Good Luck!
Tom

AutoAtlanta has them.
TacoPlate boot

Thanks very much. I think I'll try the AA route first. Not much of a risk for $6.

you are right not much of a risk, you actually do not need it, there is no risk that oil will leak out of that hole

I found a rubber grommet at the local hardware store. Keeps the wire from the metal edge of the hole in the taco plate.

Here’s a pic. Just like the OEM part
