Question Broken lower hose on F-tube (picture inside)

As seen in the picture, the lower hose on the F-tube is broken. I literally touched the thing when removing it to clean my ICV and it snapped. Saying it was brittle would be an understatement. With that I've got a couple questions...

1. What purpose does this little hose have?

2. Is it something that needs to be replaced immediately? I drove the car tonight and seems to be driving fine.

Thanks in advanced for the knowledge. Any amount is appreciated.

To my knowledge, I believe that hose leads to the fuel pressure regulator. I'm sure someone else will chime in on this if I happen to be wrong though.

A forum member Delmarco came up with a quick fix by connecting the two broken ends with a short piece of tubing and securing both ends with a zip tie. Seemed to work just fine if you don't want to swing for a replacement hose.

I noticed mine did the same thing last week, I had some extra vacuum line laying around and it was an easy fix.

Rip all of the hose off that is broken, you will be left with the 2 hard plastic pieces.

Don't go to autozone or advanced auto, they dont sell that stuff by the spool. Find a local autoparts store, a non commercial one in your town, they normally have spools of this wire, get 6 inches of it and poof, its fixed.

I did the same thing about a week ago. It's the vacuum line for the fuel pressure regulator. forum.e46fanatics.com/showthread.php?t=897616

As always, fantastic help guys.

You think a hardware store would have this line? Lowes, Home Depot, local hardware store?

I don't think so. I believe it is 3.5 mm, which is fairly close to 1/8" but double check this to confirm. BTW, the previous posters are correct. This line goes to fuel filter regulator. If there is hose stuck to the F connector, cut it off with a razor blade or you might break the F connector.

I drive a 02/2002 330i and the line running from the F-connector to the fuel pressure regulator is some sort of hard plastic tubing with ~2" of silicone tubing on either end where it connects to the F-connector and the FPR; that being said I bought the OEM tubing from RM European and replaced the section on the F-connector side. Any tubing of equal specifications will suffice unless you are actually needing the hard plastic tubing which runs the majority of the length. The OEM silicone tubing on either end of the solid plastic line is 3.5 x 7.5 mm and the part number is 11727545323.

I changed out my fuel filter the other day and I should have replaced the other end of tubing that connects to the FPR as it was also dry rotted and stiff but this was before my tubing had arrived. I'm going to do the CDV delete in the next day or so and I'm going to go ahead and replace the FPR side as well.

YES be very careful with that stupid F-connector I broke mine just messing with my upper intake boot!
