Pics of my vintage fram unit
still available on ebay when last I checked, here is the stack of photos I took of the unit as promised:
these old fram units seem to be leftovers from late 1984.... Orwell filters, creepy. This shot is with the bottom removed (opposite output) with 3 handy dandy clamps. The seat in the removable cap is just metal on metal, so I think I'm going to use some sort of silicone or liquid rubber product to seal the ring when closed.
Comes with a bunch of vintage junk and hose clamps too.
weighing in at a mighty 2-1/4", I don't feel like this mounting bracket/output adapter has the diameter to do the job for my 350. I believe since the bottom portion is flat steel, I can just cut out the center and weld in a 3-1/2" pipe that will match perfectly with 99% of all round-tube throttle body adapters.
as you can see, with the correct diameter adapter, the output potential is a sweet 3.5"!
This is a shaky shot of the interior with the filter removed from the bottom. The seat on the bottom of the unit (towards the output) is a 1" wide rubber gasket that feels quite fresh and springy. I like, I like.
a well-marked 4" outer diameter in-hole, perfect for a 4"-3" silicone adapter for the world's most common snorkel accessory diameter.
a similarly useful label on the out-hole. Is it all starting to make sense? I think the gasket on the outside is cork or something synthetic thats damn corkish. 6-bolts in this heavy steel monster can water-tight damn near anything, even if the unit is mounted by them.
as awkward as bung-talk is, there is one welded on the underwhelming output pipe. Its a 1/4" fitting or so, with a pinhole actually going through the pipe. Attached is a weird archaic filter monitoring device thats almost certainly useless for yours truly. I'll just weld on a straight piece of pipe, no more of this bung business.
This is the unit that was, game faces on, intended to be inserted in the bung hole in my unit. Again, I dont think its too useful for me, but it'll sure look cool in my 'useless parts' bin!
Anyone have any advice for my setup, please pitch it in. I know I have to throw an extra little bit of waterproofing on everything, but any input would be greatly appreciated!
