WANTED - Brake Servo Vacuum white 'T' piece with nipples

Hi.

Need the white 'T' piece with vacuum pipe nipples on that is part of the main brake servo vacuum pipework. Sits just in front & on top of the rocker cover, 3 big black pipes & often the thin white MFA / MPG vacuum pipes on the nipples.

Thanks!

James

Its one of these. Believe it is a vacuum 'check valve'. Thanks! JT
