This is a fuel line clip designed to hold larger -6AN Fuel lines and the vent to the charcoal canister to the numerous mounting studs found along the underside and behind the left strut tower of a MK2 Volkswagen golf. 60mm long.
Recommended filament is ApolloX or similar.

Attention: This is a revision on my previous fuel line holder, and is shorter to closer mimic the OEM dimensions in order to install them along the underside of the vehicle where the clips run through a tunnel. The longer version will not fit in this area.
The longer clip is designed to fit in the engine bay.
