ARE's most popular design. When using one of ARE's pans that retain the OE style internal pressure pump these scavenge pumps will pull the oil from your pan and pump it back to the ARE tank.
The pumps mount in the OEM A/C compressor locations and use the existing bolt locations on the stock LS engine block. This internal pressure / external scavenge design works well in tight locations like late model Corvettes using OEM style engine mounts as the pumps do not require engine mount relocation.
*requires ATI balancer with correct pulley sold separately.
