Kubota ST30 adapting a front loader & fitting problems

[KuboST30]

Hi. I am fitting a newer LA545 loader to my ST30 and have changed/adapted the loader post to fit the ST30 base plate. I Drilled the subframe today carefully to avoid any internal pipes a d as soon as my pilot drill went through the subframe red oil is pouring out???
There isn't any pipes near or going into the frame there so is the subframe full of hydraulic oil or did I think a hidden pipe? Any help as there shouldnt be any pipe here that i can see from checking on the outside- they are further downstream as you can see in the photo! Any ideas or info about hidden pipes on a ST30 subframe?

You going to need to add a picture of where you drilled as we don't have ST30's in the US.
Whatever you tried to attach didn't get attached. Use the icon with the Square with a mountain and a sun in it to attach a picture.
Is the subframe on the loader are solid pieces of steel, so no oil there.

Hi & thanks for your reply. Have added the image again you can see a bolt in the hole for now!
It's the subframe on the Kubota tractor rather than the image you have of the loader stabiliser bars

Ummm that's a hydraulic reservoir that you've drilled into.
You're going to need to have the hole repaired.

Suction or return line in red.

So is the su frame itself the reservoir? I was assuming i had missed any pipes as I was upstream of the pipe that you narrowed in red?
I wa ated to put a bottle through this box section- if its actually a reservoir then I could theoretically still drill my bot hole and then put sealing rings at both ends when I bolt it up? Maybe?
