Filler restrictor on E320 CDI

Has anyone removed the restrictor in the fuel filler neck?

The reason I ask is it sure is a PIA when filling, I have never used a pump that has a small nozzle like the unleaded gas nozzle, except a couple of times on a trip several years ago. I want to remove mine so I can stick the nozzle in and not have to hold the thing, bit unsure as to if it will easly remove like they did on my VW of years past.

Why they leave them in and make life hard on us owners I will never know. I know just save a couple bucks

Are you sure you're not using a truck nozzle? I think that's why the restrictor is there, to make you use a light-duty diesel nozzle.

I used the truck nozzle once. Not much of a pop off either. havent viewd the restrictor with an eye to removal, but sure nothing some tin snips wouldn't tackle. I dropped a spring in my tank from a 5 gal can of bio, so if something falls, it wouldnt worry me., I'll get my spring back when I pull the tank screen.

Again, only noticed it once so far, the truck nozzle.

Not sure how long you been in the diesel world or at least out and about a lot, but there are actually about 5 different sizes of nozzles floating around still.

That said when you use the nozzle that most pumps (non-big rig section) have here in the mid-west you are useing a nozzle that just makes it throught the first hole (if it is out of round it will not go in) and then there is the second restrictor with the flapper that a unleaded nozzle will only fit through. So what happens is you can just get the nozzle in enough to fill slowely, but not enough to let it sit in the filler all the way with the catch ingaged.

Did I make myself clear???

Hmmmm....sounds like you need to lean on yours to ream it out a bit or ram it in and out a few times?.....Out West we have 3 sizes of nozzles. There is unleaded, diesel and truck stop size diesel. Anything else would have been illegal and repalced 15-20 years ago.

I use big-rig nozzles in my car quite a bit.... (The station will sell any car that can fill from the big pump the diesel at the 3/axle price......)

Just a big gaping hole down in the tank... My grandma's 6.5L TD Chevy truck is the same way........

Yup only three sizes are authorized, but some of the odd sizes are still being used here and there. However the only nozzle that will go in all the way is a unleaded gas nozzle, and I have only seen a couple of those on diesel pumps.

All my other diesels in the past had the big mouth opening until I got the 91 and it will take the light duty truck nozzle all the way, but will not take the big rig nozzle. That was one thing I always like about our VW's, you could even use the the big nozzle on my '00 NB or the wife's '02 Jetta. You can not even use the new type of fuel container on the E320 CDI without using a tranny funnel and the old type with the flexable hose and vent is a real pain also because of the flap.

I was just asking if anyone has taken theirs out b, and how they did the job. I can always cut the thing out, but if it can be disassembled and removed I would rather do it that way.

Ream it out with a good sized drill bit.
I haven't seen what it looks like but maybe you can use a tool like a slide hammer on it and yank it out.

I have used a truck nozzle a couple times....who cares about the size (they ARE huge though)....what about the fuel speed?! it comes out of there at like 5 gallons a second! = tank spews on person filling it if not extremely careful. Even holding it in the lowest flow you can, it still comes out fast.

The "normal car/pickup" diesel pump nozzles are far better....and you can set it and leave it filling while you wash the windows.

That's pretty odd. I've been in the diesel world for 5 years and I've never had this issue and I've only seen two types of diesel nozzles: the standard light-duty one typically found at gas stations, and the wide heavy-duty truck-stop nozzle which I once tried to use in my 240D but it wouldn't fit in. I've never had any issues with the light-duty nozzles. It sounds like you live in a place that's pretty messed up as far as engineering standards go.

I am not really concerned about the big nozzle as I would only use it if it was emergency type thng. What I want to do os get it where the nozzle for PU trucks will go in far enough so as to be able to turn it loose and as you say the windows or some such thing.

That very true on the ocassions I have been in OK,TX or NM, but here in MO & AR I have seen stations that have been using the old leaded gas nozzles they had laying around I guess. There is only one national (federal size) for fuel delivery at public pumps and that is the one used for unleaded fuel only, unless that standard has been revised in the last 3 years.

I often find it funny that people think we have the best fuel and delivery system in the world, when in reality it is more like we are third world, same as in the bridges that is in all the news. So much of our road repair money gets spent for other things. Also it is a lot easier for politicans to sell the building of a new road, damn or building then it is to sell them on the idea of spending money to fix the current infastructure. It like trying to sell people on renewable fuels, diesel and smaller vehicles for general transportation. Probably 3/4 of the vehicles in my subdivision are SUV's or PU trucks and none are used for work and we do not live in the far north snow belt. These are for some reason the people who complain the most about fuel prices, go figure.

I don't leave the nozzle locked, not matter what size, because it always foams out on me.... I like using the big nozzle because if you "just barely" crack it, it will flow about the same amount as a little nozzle and creates less foam due to less turbulence and force........

I can fill fuel right up even with the fuel fill opening and not spill a drop with the big nozzle...... Takes forever to do it with the little ones due to foaming.......

I remembered on the way in to work today, gutting the fuel restrictor out of a 75 Nova I had stuffed an old skool LT1 in ( 11:1 compreression bigarse solid cam, needed Sunoco260 ), and my boss at the machine shop had me make a shop rag on a string setup to put behind the restrictor. Gnawed it out. Carefully pulled the rag-on-a-string through and caught MOST of the debris. Shop vac'd the rest.

I have never had this problem in New England. I'd just ream the damn thing out.

Post this on tech help, maybe one of the tech's knows how to get the fuel neck apart.

I wish the W123 didn't have a restrictor.. even with the regular pumps the think clicks off because of splash back or something.. I have to hold it while it fills up... darn I could be doing other things like cleaning the window or something
