I would like to know the amount of oil/capacity of a Generac
1536-1 high pressure pump. It is a 2100 psi , type 4200 cp,
2.0 gal/min. This pump has no eye glass to see the level,
and no drain or set screw to watch oil run out when filled properly. The hole on top of the pump allows for the mating of the engine shaft to the pump. This hole is the only way to get oil in the pump. I don't want to over fill the pump to any help on how much oil goes into the pump would be greatly appreciated.

First Thanks for the heads up on Google, never used it before always used yahoo on searches.
Second The owners manual searched on google was updated and had the type of oil used as well as the amount . I was going to use the same oil as one used in a video which was a non detergent 30w. The updated manual called for 80w-90.
quite a difference. Sorry I tried your patience !!!

Why didn't you bother with a simple Google search?

Forgive me but I get really hacked off that people seem unable to raise a finger to help themselves. Literally 30 seconds was all it took to find an exploded diagram, owners manual and a figure of 140 ml (See page 11).
