I was also surprised by that. My intake screw was vertical, but the catalog only shows the right-angled version. I still have my vertical intake screw; I could give it to you if I can find it.
I actually built an AFN cover for my 1Z, and it's now pressing on the 1Z cable, which is why I already bought some AFN cables, but they don't have the connectors .
'I've finally found the supply line. It's a molded plastic line with rubber hoses crimped on both sides, and of course, the straight nipple. The VW part number is 1H0 130 307 AC, which is also listed in the catalog, but it's only sold as a complete unit, so the individual nipple isn't included.'
What do you need right now? Just the nipple, the entire pipe, or also the return line?
