Spin-On By-Pass Filter Installation and Servicing Instructions
attaching the filter mount
1. Survey the engine compartment for possible mounting locations. Solid structures such as the firewall, fender well, radiator support or frame are normal locations. (Do not mount on engine.) Refer to diagram B for minimum area requirements and consider accessibility for servicing.
2. Refer to diagram A for preferred mounting positions.
3. When the location has been determined, use the mounting template provided to locate and mark mounting holes. This can be easily done with a center punch and hammer.
4. Install adapter fittings (BP-208) on filter mount using provided thread sealant as noted in diagram C. If desired, 90° angle fitting (BP-52) may also be used. Using a 7⁄16 wrench, tighten fittings 2-3 turns beyond finger tight. Keep in mind the direction you wish to have the hoses intersect the mount.
5. With a 5⁄16 drill bit, drill out the previously marked mounting holes and attach the mount using the 5⁄16 bolts, nuts, small washer and fender washers provided. Bolts should be tightened to 16-18 foot pounds. 1⁄2 wrenches or socket will be required for this operation.
6. Fill the By-Pass Filter element with the same motor oil being used in the vehicle. Lubricate the filter gasket with oil and spin filter onto mount. Tighten per instructions on the filter.
Oil Supply
1. Locate oil pressure sending unit (see diagram E). Remove unit and install “T” (BP-33) using thread sealant as noted in diagram C and tightening 2-3 turns beyond finger tight.
Note: See diagram G if oil pressure sending unit has a 1⁄4 N.P.T. thread.
Note: Special adapters may be needed to install “T” on some engines. Refer to the Oil Pressure Sending Unit Information Guide. Occasionally, additional fittings may be needed.
2. Reinstall sending unit in one opening of the “T” and a fitting adapter (BP-208) in the other. Use thread sealant and tighten as noted in D.1. Use 90° Street Elbow (BP-52) if necessary, keeping in mind the direction you wish the hose to intersect the fitting.
3. Measure the amount of hose (BP-206) you will need to run from the Oil Pressure Sending Unit “T” to the filter mount fitting labeled IN. Additional length will be required to accommodate engine movement during operation. Using a utility knife, squarely cut the hose to the proper length.
Note: The hose and fittings supplied with this kit have been matched to provide max- imum performance and life expectancy. Interchanging with other types or brands is not recommended and should be avoided. Should additional hose be required, it may be obtained from your AMSOIL Dealer by ordering part number BP-206.
4. Install hose fittings (BP-261) on both ends of the hose following the instructions noted in diagram F. Tools required are one 9⁄16 wrench and one 11⁄16 wrench or vise.
Note: Do not use any form of thread sealant anywhere on the BP-261 hose fittings.
5. Route and connect the hose assembly making sure the hose does not contact any hot or moving surfaces or sharp edges. Ensure a minimum of a 3⁄4 bend radius is maintained at all corners. Also, bends in hose should not begin at hose fittings. Using a 9⁄16 and 7⁄16 wrench, tighten hose fitting swivel nut to 130-150 inch pounds or from finger tight, rotate an additional 120° or 1⁄3 of a turn. See diagrams D and H for additional details.
