vacuum pump outlet
does anyone know where the vac pump outlet is?
My pump check valves seem to be stuck ( air pushes in and out of vac line )
little to no vacuum so i sprayed sum wd 40 in the line and voila vac is back but it acted up again.
Sooo when i spray wd40 in the vac line where does it go after the vac pump?
Is there an outlet internal or external?
can i flush the pump with sum mild solvent to clean it or will the solvent end up in the motor?
Should i just pull it and rebuild?
thanks---Steve
oh-- 84 300 SD with newer style pump ( screws in front cover )
