Gti jet pump rebuild

[Bma1977]

I need to rebuild the jet pump on my 2010 gti 155, is it worth buying the bearing pusher tools I've seen online? Also is the cone full of oil or a marine grease I cant seem to get a solid answer on that.

Any help is appreciated

I believe that if the cone has a little screw is full of oil
if no its grease
