I'm sure these are Djet hoses, but can someone confirm and inform where on the engine they go to. There are 2 long-ish hoses that come out (or go into ) the corner of the engine compartment on the driver's side (under the relay board). I don't remember these on my past 914s.

Also, where could they lead to ultimately... the longs, then where ?

For early 1974 cars and before, two hoses come from the fuel tank area for the charcoal canister on the fuel tank, to the engine bay. Its not a D-Jet thing, its all 914/4s.

Late 74 and later had the charcoal canister in teh engine bay and no need for the hoses.

This is a '72 w/ 1.7 & stock djet - which apparently is of no consequence as far as these hoses go.

So - when I switch over to my 2.0L dual weber engine.. is there an easy and accepted method to incorporate these hoses (and the entire charcoal canister system) ?

PS- thanks a ton for posting the diagrams, very helpful.

Follow the arrows. Note the one that connects to the fan shroud. That air goes to where ever the canister is located and back to the stock air filter housing ( a carb draw off). In theory it should help with the fuel stench you get with carbs. The canister you have may be filled with spent charcoal.

Vent hoses from gas tank and carbon canister in the front trunk. The come out the driver side front wheel and go down under the rocker panel.

On carbs I run the return line to one of the air cleaners
