It started with the external oil filter, but I recently decided to convert all* of my VW’s fuel lines to -6 AN fittings… you know, those red and/or blue aluminum fittings on the end of stainless steel braided line? The advantage is that they’re very secure, leak-free connections. The downside is that it’s very, very expensive to get all of the line and hose ends and connectors and adapter fittings. (Expect to pay over $10 a foot for your line and $6-$30 per fitting.)
Here’s the Canton Mecca oil filter with -8 lines.
Holley fuel pressure regulator run under the rear tray. Notice the two -6 bulkhead fittings run into the engine compartment…

A view of the whole thing. Fuel fittings on each side of the engine, ready to connect to my dual Weber 44s
*technically, the fuel line through the body is still original steel fuel line.
