My 1975 Highboy has a severe duty air cleaner(oil bath)

How much oil is supposed to be inside this?

As part of some of these severe duty air systems I have also seen a plastic molded fresh air induct tube which attaches to the radiator core support and grabs air from an opening under the grill. It also has a flexible tube that goes to the snorkel from this air induct tube , kind of a ram air set up.
Does anyone know the part number for this air induct tube or maybe have one for sale?
Thanks

My 70 used to have an oil bath air cleaner.... I swear I remember seeing a fill level line somewhere.

 

The fill line mark is near the bottom. It doesn't take as much oil as you might think. The idea was that centrifugal force would throw dirty particles into the oil.

 

Thanks for confirming... that particular brain cell in my head survived!

 

1 down and 37 to go?

 

Found it!
Thanks

anyone know the part number for the plastic induction tube that mounts to the radiator support panel, not the flex tube LMC sells.

Thanks in advance

Ford: Not available by itself, only sold with the flexible duct.
