The BUGPACK thing is a breather box, looks like the rocker covers are vented, unnecessary on the type 4 but common on tricked up type 1 engines. Do you know what the engine spec is? R6 will leach fuel so will R7, R9 less so, 100% bio fuel tolerant hose is best. I bought mine from VW Aircooled Works. https://www.vwaircooledworks.co.uk/Fuel-Hose-Kit---Full-details.html
Looking underneath there's quite a fare few metre's to replace ! . yes the rockers are attached via the orange tubing (so vented) . on the engine spec I was told around 2100cc. Whilst we're on the fuel subject , any cause for concern on the fuel pump .
No braided rubber and braided Teflon are worlds apart . The Teflon uses an olive and aluminium fittings
