LS oil feed fitting for OEM engine block
Dailey Engineering LS oil feed fitting for OEM engine block, 16mm thread to -10 flare.
This fitting is designed to be installed into the lower-left port just above the side bolt for the #5 main cap. When the original plug is removed you can look inside the port and see the OEM plastic oil galley plug (shaped like a dumbbell) that was installed at the factory. This plug should not be removed as it will keep the high-pressure oil from back-feeding into the oil galley going to the OEM oil pump location. If this galley plug is removed you will need to seal the ports at the front of the block where the OEM oil pump feeds the block.
Crush washer included
The pan gasket will need to be trimmed for this fitting to be installed
