Conversion check valve

Can some forum member please tell me what check valve you installed with your conversion to vacuum.

ATE part # 191611933 Some applications 77-79 Porsche 924, 75-79 VW Rabbit, 67-95 Volvo

Thank you Alan ,thats the one I have together with the 11/32 vacuum hose,did you have a problem fitting the valve into the hose.?

My pleasure. It’s been at maybe 15 years since I did it, so I can’t say.
My XJ40 has moved on. I do see a note that it is a tight fit, maybe a
dab of silicone grease.

Thank you,I though maybe they had sent me the wrong valve.
