I have a couple of choices of oil fillers to use with my aftermarket oil tank. There are notable differences and I’m not sure why.
One is aluminum, the other steel. Overall length. The aluminum one is a bit longer which could make filling easier. But more intrusive. The vent hose sizing. Aluminum one is for 25mm hose the other is 13mm. I’m guessing they are designed to terminate at different devices? I’ve seen from diagrams that some end at an oil overflow bottle. Where did the hose end up on the original 914-6? Thanks for your help. Attached thumbnail(s)

Btw why you really don’t want the vent to connect to the air filter is that when you accidentally overfill the tank and that’s a when as everyone has done it at least once or when you drive aggressively the excess oil gets consumed by the engine and you get a ton of smoke out the tail pipe which will also effect combustion effect and could be detrimental to the health of the engine especially if running full tilt. Stock -6 engines really were not high performance so didn’t really matter
Simple answer mine is designed for puke tank just like GTs The aluminum one designed for attaching to stock filter but could be adapted to puke tank. |

(IMG:style_emoticons/default/agree.gif) Been their done that. I thought my 3.2 engine died, but I accidentally over filled the oil tank during an oil change. I installed a puke bottle after that fateful day. I have a stock 914-6 filler pipe, but a smaller, less obtrusive hose would be nice to the puke bottle.  |
