Default Ventectomy Pics

I want to perform the ventectomy but there used to be a thread with pictures. I can't find it anywhere. Even the one in TDI 101 doesn't have pictures.

Does anyone have a link to one?

I just hit the button with the end of the pump nozzle. Get the same effect without having to tear into the car.

Follow GWillie's process. It takes 10 minutes and is quite easy to do. Works a lot better when done.

Oh I know, but it isn't like it is a difficult task.

Of course not, but one less thing you need to worry about when it's -20 outside

You gain about 2 gallons of fuel capacity.

I did this to my son's new (to him) Jetta a couple weeks ago. Forgot how to do it, it had been so long, but gwilli's pictures jogged my memory. Took about 5 minutes.

It's a great mod, makes filling the tank easier. After a while you can notice when the tone of the whistle of the air coming from the vent changes and it's time to slow the pump flow down to top up. Tank after tank of 700+ miles makes it worthwhile.

Meh, I tried this and could get the damn thing out. So, I just used some pliers and bent the plastic surrounding the button so it would hold it open. Would have saved me a hour of my time.

As a side note, I left my cap off yesterday and started the engine up and it drained the filler neck down to were I couldn't see diesel any more. Wounder how much more I could have got in there. Will have to experiment next time.

Have you ever had the displeasure of being on a motorcycle mid curve and hitting a patch of spilled diesel fuel? It's like being on ice, so please always remember to put your cap back on...

Recently did this on both my cars. Hardest part for me was figuring how to get the black plastic collar out! I was afraid of breaking something (plastic door and hinge), but finally just decided to push/compress it some and then swing it out- wasn't aware that door and hinge came out with the collar. After that it was pretty easy. Remember to line up the neutered plug properly so that it pops back in fully; note the orientation of the straight edge on the valve body.

First full tanks on my cars I got 729 miles and 746 miles. Had been getting about 100 miles less before. Clearly I'm getting 2 gallons more in these things.

For filling technique I just go by pump shut-off, as I'm not going to train my wife on the finer points of fully topping off (and risking spillage). I run the pump full throttle until it shuts off and then I run it again at 1/2 throttle. I fill up at the same truck stop and pump (most of the time) in which case I can expect to be fairly consistent such that my mileage calcs are pretty accurate.
