For the life of me I cannot find the various grommets for fuel lines going through the tunnel. I need to find pair at the front, rear, and they two that go through where the battery is mounted. Anyone know where to find these? Or the sizes at least so I can just get something similar?

If you're looking for the one that is at the front bulkhead where the fuel lines enter the tunnel at the front, they are NLA. Put a WTB in classifieds. I did that recently and a member responded.

Some of the other ones can be found here at Tangerine Racing:

Not sure this will get you all of them, but should put a dent in your needs.

The ones on the engine shelf are VW front wheel speedometer sleeve 111 957 861

Part #111957861 also for Rubber Grommet Fuel Line, and Brake Reservoir Line

Tangerine has a great kit with all the grommets necessary. I just bought two full kits with stainless lines last week. GREAT customer service!
