Air Cleaner Insights, 914-6 Correct Options

[DennisV]

Is this air cleaner correct for 1970 914-6? Am I missing any components?

I went through the other air cleaner threads I could find. A couple things about our plastic one that seems curious when I compare it to the photos I'm finding of others identified as 914-6:

1. No clips or inlets for cold start fuel lines
2. Large to small outlet plastic fitting

Thanks.

P.S. I am unclear about the fittings. My best guess is the small single port metal one is a water drain valve and big plastic one with two outlets is oil breather? Not sure how to connect either.

Sounds like Ben has tried this. I was assuming that the plastic box , whether carb or MFI has the same shape and size to accept wire long version clips from the correct carb buckets Certainly could be wrong on that.

There are two versions of metal carb buckets - one version (on the left in the photo) have higher walls on the inside diameter of the bucket. One version does not have these higher wall extensions. Only the buckets without the extensions will work with plastic boxes. I think the higher wall version is for metal boxes.

The incompatibility of these different buckets may be the reason that some have had problems making plastic boxes work. See the picture below and the link shown in post #7 above where Rory shows a different picture of the same bucket issue. I see no reason why you could not trim the higher inner wall to make it even with the outer wall to make a bucket intended for a steel box work on a plastic one as suggested by Rory in the same linked thread.
