# Part number Description

1 standard pressure spring, white
1 M-29509-BP black O-ring

Pump specifications:
· over 30% higher volume capacity pump than the stock LS1/LS6/LS2 oil pump
· displacement of 1.26 in3/rev (compared to the 0.95 in3/rev on the stock LS1/LS6/LS2 pump)
· 8/9 gear set with thicker gear than the LS1/LS6/LS2 stock pump
This oil pump is supplied with a high pressure relief spring installed in the pump. If a lower oil pressure
is desired, remove the red spring and replace it with the enclosed white spring. The white spring will
provide a roughly 15 psi reduction in peak oil pressure. With the installed red spring, the pressure relief
valve should be in full relief at 75 psi while with the white spring this will occur at roughly 60 psi.
Torque requirements: relief valve plug torque 12 Nm (106 inch-lbs)
Note: changing the relief spring will not change the low rpm idle pressure.
Two different pickup tube O-rings designs exist - Figure 1 usually applies to truck applications and
Figure 2 usually applies to car applications. If the end of the pickup tube that installs into the oil pump
looks like Figure 1, use the supplied green O-ring (the stock O-ring should be green or red in this ap-
plication). If the end of the pickup tube that installs into the oil pump looks like what is shown in Figure
2, use the black O-ring (the stock O-ring in this application should be light blue).
NOTE: this high volume oil pump is thicker than the production LS1, LS6 and LS2 oil pump and does
not fit in a stock timing cover with most aftermarket double roller timing chains.
