912 Crush Washer on bottom banjo bolt

These are common parts.
Just Google "16 x 22mm Washer".
They are readily available on Amazon and eBay for way less cost.
A pack of 10 can be had for under $6 delivered.

Even though it may look like the banjo bolt make sure it isn't the hose oozing oil.

If you do take the banjo bolt out to replace the crush washer make sure you have something to catch the oil when you remove it. It will be quite a bit.

Thank you! I'm changing the oil during the 100hr inspection.  I'll double check the house clamps. I was going to order some washers on eBay/Amazon, but was told to stick with rotax. 

I'm sure it wouldn't make a difference but had to follow the owner's request.

Hose...lol.....

If that doesn't fix it, consider another source. The back of the oil pump bolts to the front of the crankcase with an o-ring in between. The split in the case runs across the o-ring and provides a seep path, especially if the o-ring is old. Helped by the air blast, it then follows the seam to the banjo where it drips off and makes a mess.
