I used the end of a hacksaw blade to roughen the surfaces inside the flange groove, 80 grit sandpaper elsewhere.
For the break along the flange side, I used a Dremel with a ball burr to cut a groove on both sides, then scrapped the epoxy flat to the adjacent surfaces.
I went with J-B Kwik epoxy, it's easy to work with, fast setting and a close colour match.

Thanks to all for their suggestions.

Glad it worked out for you. JB Weld fixes anything except a broken heart. 😆

You might try Beemerboneyard to see if they have a used part. They will also put you on a waiting list if they don't have one today but get one in down the road.

Many of these on e-bay for less than $40.

I had checked E-Bay and they are certainly available, the shipping + duty + exchange kills us north of the border. Repairing was my first option.

He says its polypropylene and a quick internet search says PP-GF 30 is 30% long strand glass fiber reinforced polypropylene. So now I know what I'm dealing with. Solvents are ineffective on polypropylene. The joining method is heat, and usually some sort of tooling / fixture to align and control the pressing together of the near molten plastic is required. Since I have to maintain a relatively flat surface where the flange meets the filter / air box, and I have nothing in the fixture department, all I can do is try some epoxy with lots of surface prep. My previous epoxy tests were on the smooth exterior surface of the snorkel, abrading the joint and surrounding area should help with its adhesion. Crossing my fingers...
I'll post some pics if I can find a free on-line 3rd party hosting site (damn Photo-bucket).


Well, the good news is that polypropylene is supposed to be easy to weld according to this: http://www.kingplastic.com/tips-for-welding-thermoplastics/

There's a bunch of youtube videos on welding plastic - including some folks that use a small torch or soldering gun for heat instead of dedicated plastic welding tools.
