the junctions are 2.75" to 3" hump hose adapters (these get heavy use in large diesel engines) designed to move when the engine twists. I thought thay where a nice addition since just about every home grown intake I have seen so far uses 3" radiator hose with some sort of bushing. I will probably switch the one connected to the AFM to radiator hose when I put a larger AFM in with a 3" OD inlet.

And here I was, thinking you got them from the sewer drain section of Home Depot. Floating unions for drain pipe. Looks exactly like them. They might be vulnerable to fuel, but there should not be fuel at that point. Easily replaceable if they are.

I'm thinking this approach would be far superior to over $200 (!) for an Injen intake or whatever, for my 3.4 swap. I hate relying on K&N (or equivalent) filters, but a foam sock over the outside as a prefilter should be adequate, with an airbox built where the battery used to be.
