Vacuum conversions kit question

This is a question is for any forum member who recently purchased a kit ,Are the still recommending a check valve with part no.191611933 from ATE. and a vaccum hose of 11/32.

I got my kit and it included the check valve. all works well but I still come up with Blake pressure low fluid low etc.

I am thinking of the conversion too. Would you please post or DM a reference to the kit you got?

The firm name is, jaguarspecialties. com, I purchased mine a number of years ago and only now got around to installing it.

Quite helpful as well, I am currently working with Andrew from jag. specialties try to eliminate fault codes.
