bulk AC barrier hose Help

[Black_Hat]

adding a additional stock condenser to my 1991 964 turbo inline . the high pressure hose is small ....a #6 is too big .



The hose I'm looking for is 15mm outside 8 mm inside - outside is 1/2 " or a little over inside is 1/4 "

I've done this "upgrade " before but I took the extra hose off the donor car ....the hose is made by continental

the writing on the small piece I have : 22/92 CONTI - CAC 4 4107DN 8

I just need some bulk hose.

any one know where to get some?
