Yes.. the suction/scavenge lines will pull a
vac.... also remember when you buy a pump that
1 port is the pressure port, so a 3 port has
2 suctions lines and a pressure.. I ran a 4 port
on my R3 block.. 2 in the pan and 1 in the valley..
this was a dry sump block so the valley was sealed
and had to have a line up there(unless you drilled
return areas)
