Hello my name is Marcus,
I got an 1973 Datsun 240Z in my garage that i'm trying to get working.
Right now i've been looking on the internet for Needle valves with product number
16101-E8811 and 16101-E8810
I need this in ONS "Old new stock" without the rubber tip on them.
I haven't managed to find what i'm looking for so that's why i'm reaching out to you at this forum to see if there is anyone here that knows where i can get this Needle valves.

Thank you in advance,
// Marcus from Sweden

Just about any parts supplier should have rebuild kits for the SU's. Z specific suppliers like MSA or ZCD will definitely have them. Also Ztherapy specializes in these and likely sell the parts as well.

Ztherapy will have what you seek, for sure.
