How to remove the fill up pipe restrictor?




On W210 diesel, I had to use funnel, but it work OK.
Now on 320 Bluetec it is getting very annoying.
Not only restrictor has very small hole, with flapper deep under the neck, so funnel has to have long extension, but the pipe foams a lot, than gargles -occasionally spitting some foam back.
I was checking the restrictor, but it seems to be spot-welded inside the neck and it is 2-stage where the flapper behind is not accesible at all.
Anybody found the way to get rid of the gizmo?




I hope the hose will go below venting connector and prevent gargling.
Not the best solution as hose is still much smaller than the fill pipe, but should be big improvement to fuel spitting back.
Plan to drive to truck stop in about 10 days, so will report back.

Can't help but wonder whose little bit of brilliance it was to put those restrictive holes in the filler pipe, but I'll bet there was a lawyer involved.
If you figure out a way to make it go away, post it up!




I did turn the can upside down for full flow and all the fuel went with not even a drop spilled.
Can't wait till I test it with "big gun"
Will post the results with picture then.




The only trouble is storage it after use as diesel drips for long time.
I cut a piece of 4" drainage pipe and put the funnel in it, while having some paper towels at the bottom.
