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.

I’ve read about a few cases of 6’s getting hydro locked due to rain water getting past the seal and into the buckets.

Wow, great find on the metal drain tube fitting. I vaguely remember seeing or having one of those but had no idea what it was for. That is some obscure minutiae right there! As is the Shell sticker insight!

I agree the clip on the back was to secure the cold start cross connection hose. See below. Also note on this box the what I think are correct cold start hose clamps. And also the plug in my vent fitting appears to match perfectly with the one Rory shows. Also see the same height walls on the plastic compatible buckets. These buckets work on carbs and the mag stack MFI as shown in the other photo.

The one other piece of obscure minutiae is the inclusion of the “fire screen” in the vent fitting that is pictured below on what I believe is a 911 MFI plastic box. And seems to appear on the six box Rory shows. This screen is not there on my six box? Maybe just missing.

By the way, the six box and this 911 MFI box are identical. Only the snorkels are different. There certainly are 911 plastic boxes with slight variations (indentations on the bottom) but the basic boxes are identical in shape form and ( I suspect) function.


Oh and found the link to this very comprehensive discussion on Early S Registry. https://www.early911sregistry.org/forums/sh...rious-MFI-years
