Hi, me again with my never ending DS650 questions.

I bought a used replacement stock from ebay for my DS650. Problem is the idiot who sold it to me detached the hose that fits to the res so it would fit into the box.
So the oil leaked out of it and all over the place.

The seals and every thing look so I,m going to try to refil the shock with shock oil and then with the nitrogen.

My question then is how much oil should I put in. Anyone know the exact amount to measure?

Thanks again
