Finally getting around to installing my aux vac pump (JC4 from Applied) - or attempting to. Bought some PB Blaster to loosen the very rusty bolts on the booster so I can hang the JC4 bracket. Went to NAPA to get vac hose, but the largest they had was 3/8 and it wouldn't fit. Came home and measured the hose barbs on the pump, and now I'm really confused. The one that points tangential to the pump rotation (presumably the suction) measures about .630". The one that points perpendicular to the pump axis measures .540" Yet I understood this thing was supposed to go inline in the hose that runs from the manifold to the booster, so that kind of requires the same size hoses on input & output.
Can anybody clarify this for me?
Thanks
