How to plug oil canister during purge?

[MacPara]

I am about to fill my 912 with oil for the first engine run. The one thing I haven't found an answer to in 912-018 and related posts is how to plug the in-fitting of the canister. Does anyone know what thread this is? Any other ideas how to effectively plug this hole during the purge?

You can use one of the plastic yellow caps the engine/cooler came with.

If I could just find them! Wanted to keep 'em but probably threw them out :-(

Get a Helper

Just have someone hold there finger on the tank fitting while you spin the prop. It only take a minute...........Tom

Helpers are even harder to get around my carport than finding small yellow caps. I kid you not! Inspired by Joeri's suggestion about the yellow cap and knowing that I must have retained these little fellows somewhere, I searched the shop again and found them.
The purge was uneventful and the pressure required for this is so small that I could have used a heavy application of painters tape over the in-fitting as well.
