Stock bpv hose size

[vCo2v]

Anyone know what the stock hose size is for the bpv inside diameter? I'm trying to get a reducer for my Bosch bpv from 1" to whatever

For anyone who wants to know it's 3/4"

I don't know if its still available, but there is a stock rubber hose that tapers from 1" to 3/4".

Here is a link showing the part as Kragen (B70773), but the link is dead. Kragen is now O'Reilly I think.

This looks like the one. Chop off the tail to make it fit.

bought this for the bottom piece https://www.pegasusautoracing.com/productdetails.asp?RecID=11144 and this one for the one that connects to the intercooler piping to the throttle body (slightly smaller than 3/4) https://www.pegasusautoracing.com/productdetails.asp?RecID=11094 plus it has a bend to make it easier to reach, I'll take a picture once I get it and install it.

Fwiw it's not that difficult to mold hoses especially if all you're doing is changing the ID. Bends aren't all that hard either.
