Have searched through this tech forum and found the question asked many times, but none with an answer. What are the diameters of the vacuum lines to a D16Z6 engine. Mine are all original and while I think OEM is great, I just want to get the select lengths. My problem with checking my existing hosing is the ends are typically stretched from the nipple they cling to and I dont want to cut them off without a replacement in hand.

 

Hondapartsnow quotes a 3.5 bulk vacuum hose for my d15b7.

Whether that ID or OD not sure.

And my booster hose is printed 11/32.

Maybe you can check hondapartsnow.

 

Found this elsewhere since I now had a reference to go on.

"95005-35008-10M [ this is a bulk hose, with no numbers printed on it]
95005=type of hose is general applications
35=3.5 mm inner diameter
008=lenght in meters
10M=Gray hose

I took this from motorcycles guides, my guess is that honda have shared parts with cars, I also checked on EPC parts catalogue and the reference ID was the same.

The whole code is described like this
95xxx-yyzzz-w0M

=== 001- fuel hose
=== 003- vinyl hose
=== 005- vacuum hose
