The OM617 Oil Filter Relocator allows you to eliminate the factory canister filter housing and replace it with a spin-on style filter head. This gives you the freedom to mount the filter wherever you'd like. On the Toyota swap, it eliminates the interference with the parking brake bracket. On the OM617, it allows you to remove the injection pump cover to make adjustments without having to remove the filter housing like you do with the factory canister housing. The adapter is clearanced to allow easy installation and removal of IP cover, unlike other kits on the market. Accepts 1/2" NPTF fittings. DO NOT INSTALL ALUMINUM FITTINGS DRY! Fittings should be anodized. If not, apply a lubricant before installing to prevent galling.
