Air Pressure from Jacobs pump?

[BillGotthelf]

Anyone know how much air and max pressure fr the engine driven air pump that goes on with the Jacobs exhaust brake? I want to mount a storage tank and air horns.

Isn't it a vacuum pump?

 

[BillGotthelf]

I don't know. Better read the book the dealer gave me.

Yes, its an otherwise useless vacuum pump
