Did some PM's on the 353.. mostly brake stuff.
TM says put in 2fl oz of oil to keep the hydrovac felt and leather supple and make a seal.
FYI 2 fl oz is approx 1/4 cup. I use Permatex hydraulic oil. Comes in quarts at places like Tractor Supply. Looks like 1 qt will last a couple of years.

1/4 Cup is incorrect, consult your TM and LO again.

1 FL Oz for the rear, and 2x 1/2Oz for the center plate.
1 + .5 + .5 = 2 Fl Oz
(9) HYDROVAC CYLINDER. Lubricate every 6,000 miles with
(SA) shock absorber fluid, light. Remove pipe plug at center of rear
shell, also plug from inside elbow at center plate. Apply 1/2 oz of
lubricant through each plug opening. Replace plugs. To insure
proper spread of lubricant in cylinder, start engine and make 3 or 4
severe brake applications. Early vehicles are equipped with vacuum
cylinder at left side of vehicle. Every 6,000 miles, remove plug in
rear of cylinder and apply 1 oz (SA) shock absorber fluid through
plug opening. Replace plug. Every 1,000 miles lubricate idler lever,
ahead of vacuum cylinder, with (CG) general purpose grease, sea-
sonal grade.
I 'splain things a bit different I guess.
