Im chasing up a fuel cap for terry (wombatventures) and have found in my spares 2 differnt sizes for late model (70+) caps.
anyone know what size is for what year, did they change the fuel neck size.
i can do some measurements and post up some pics if needed.
cheers

I checked the filler Peter.
The larger cap would not fit in the space under the fuel flap. Ours is a 71.
Would the larger one be from a late Kombi or Beetle? Bert has a locking one for his 72 but it seems to be a screw in cap.

i will do some checking over the weekend. i think the larger one i stole the gasket off for my 72 when i had it so maybe 70 71 were smaller.
i will check my cars in the graveyard tomorrow if i remember. think i have a 70 and a 73 so see what i can find out.

Luftung (on smaller cap) means "ventilated" (but ohne means "without", so it must mean "NOT ventilated"). This definitely is an original late type 3 petrol cap; those original caps had the red fibrous-filled looking/rubbery seal.

Luftdicht (on larger cap) means "air-tight". I had one just like that, and although it didn't fit the fuel-filler, it did perfectly fit the OIL-filler (the little spring tabs that hold it on match too) -- and it looked EXACTLY the same as the usual type 3 oil-filler cap - except it had no integral dipstick... so could it be an oil cap? (Did any of these engines not have the integral dipstick?)

checked the graveyard and found the smaller one fits the 70. checked the 73 and yes its a screw on cap.
all i can think of is that the larger one must be 72 only as i am sure i stole the washer out of it for my 72 when i had it.
dont know about oil cap ??? thought all type3s had integrated dipstick...
someone will know i guess
