Need a Part No. -- Plastic F-tube from Upper Air Intake Boot

Hey all...

I replaced my oil separator recently and the only thing I broke is the little plastic F-shaped connector that comes out of the upper air intake boot (which is connected on the front side to the MAF sensor, and the lower intake boot on the back side). The bottom of the F-shaped tube goes into the boot and the two other pieces are connected to hoses. I believe one of them is from the fuel filter, not sure.

Does anyone have a part number for this? Before you suggest realOEM, go look there yourself...thanks.

BW

I don't think that's the one....especially since this piece only serves as a gateway for air/vapors to go through. I'll get a picture of what I'm talking about and post that. Even the guys at the dealership thought it was the part you're mentioning. I would suspect this part to cost under $5, to be honest.

Then maybe the 'air shut-off valve' Interesting that for my car, there are two diagrams...one with this shut off valve, the other without.

Anyway, it's not a $5 part if it's this...more like $50.

HTH, but a photo would help even more!

Here's something from your car...looks like an F (sort of) fits in upper air intake boot...but remember, these are only schematics...the pictures in realoem or even at the dealer aren't always life like!

HTH,

Doug

On the RealOEM diagram it's L-shaped, not F-shaped. I think the second nipple broke off on the RealOEM diagram, just like it breaks off on our cars.


Or, in slightly more seriousness, it's because that second vacuum line goes to the fuel pressure regulator on the fuel filter, and older E46s use fuel filters without pressure regulators. RealOEM uses the same vacuum boot diagram for cars with and without the fuel pressure regulator. The diagram is accurate for the older cars and misleading for newer cars.

BMW do not have those as individual replacement parts.

I also broke my rubber connector vacuum tube that goes to that F connector and was told I needed to buy the entire amf boot unit to get that tiny rubber tube.



Long story short: I went to Pepboys/Autozone/R.Strauss with Solid Jake and bought a vacuum rubber tube length for
about $1.39 a foot.

I know this is a long-dormant thread, but you don't happen to recall the interior dimension of the vacuum tube you bought off-the-shelf, do you?

Chris,

When you find the hose you want in realoem, it'll typically list the dimensions...seems like almost all the vac lines on mine are the same 3.3 x 1.8 ...I think that means, correct me folks...that it's 3.3 mm opening and the walls are 1.8 mm thick...I measured a section I had, and that's as close as I can figure...so total diameter of 5.1 mm

But find the hose you want and you should see dimensions listed there...and I'm pretty sure of my measurements, so think that's how they designate their hose sizes...

HTH...Del will know if he comes around...and I'm sure he will...now that he's given up modding his car, he'll have extra fanatics time for us all!

Doug

nah...and the thing is I have an extra 6 inches of it just laying around.

I can ship it to you for free if you want. How soon do you need it by?

PM me your location.

Here is the part number for the vacuum hose 11-72-7-545-323. I don't know the dimensions but like Doug said, if you go to realoem.com you can find the dimensions. I bought the hose at my local dealership for $15.57 but I'm sure that you can but it at an auto parts store for much less. I was already at the dealership to get the little F shaped connector so I didn't bother to go anywhere else for the vacuum tube.

I accidentally just broke this hose too.

To make sure I'm looking at the right hose dimensions: http://www.realoem.com/bmw/showparts...03&hg=11&fg=45 part #7?

What does this hose connect to at the opposite end? Is it safe/possible to drive the car with it broken like this?

The item number for the vacuum hose is given in the post above the one you made. It's the right part number because I had to buy it also when I broke it during a CCV replacement.

I'm wondering what this does as well. The F connector was broken in my 330i (recently purchased) and I just realized it. It seems to be driving fine still hence my curiosity.

found the part at bmw for under $5 so I'm replacing it anyways but i'd still like to know what it's for.

On the F-connector the bottom hose comes from a second vapor line off the fuel filter, and the top hose goes to a vacuum pump onto the intake manifold. I replaced my whole hose (bottom one). I ripped it cleaning my MAF and throttle. I thought it wouldnt bother til the SES came on....Long story short, I changed the complete hoses I got from NAPA and the SES light cleared itself. easy DIY.
