1.   In order to keep the oil flow restriction within the manufacturers limits always use the shortest possible hose length with the correct inside diameter and try to avoid elbows wherever possible.  Standard hose assemblies are available in dash sizes # 10, 12, and 16 and are standard overall length of 1 meter (39.4”).  Custom hoses and fittings are available on special request.
2.  Keep entire system clean during installation in order to avoid contamination.
3.  Prior to hose installation please note the “IN” and “OUT” markings stamped at the connections on both the adapter and filter-head.  Remember the oil flow of a filter cartridge is from the outside of the filter to the inside threaded part of the filter.  We recommend using hoses that have NPTF male pipe thread on one end and a SAE-JIC swivel with a 37-degree flare fitting on the other end.  In this way each hose end can have a specific port.  We recommend installing the male NPTF hose end to the outlet (“OUT”) ports of both the adapter and filter-head.  Improper installation of hoses will result in the total shutdown of the oil flow to the engine with the possibility of destroying the engine.  For this reason, it is very important to check the engine oil pressure before and after installation.  An incorrect hose will indicate no oil pressure.  On large engines which utilize two remote filter assemblies it is extremely important to make sure hoses are correctly installed.  If one of the two filter assemblies were incorrectly installed the engine would still show oil pressure even though the oil flow was reduced by 50%.
4.  When installing the hoses and fittings to the adapter and filter-head’s NPTF ports use Loctite PST 567 or equivalent.  This high temperature Teflon paste helps lubricate fittings to ensuring a leak free seal.  Loctite 567 has a curing time of approximately 72 hours.
5.  To eliminate leakage, remember to lubricate the adapter seal with clean oil before installing.  Torque the adapter to the engine the same as required for the filter cartridge.  Over a period of time the adapter seal may need to be re-tightened.
6.  At this point you are ready to mount the filter-head to the engine in an easy accessible location.  Utilizing the optional steel angle bracket you can bolt the bracket to the engine or weld it in place.  The filter-head can be mounted in ab unlimited number of configurations as long as the filter cartridge has an anti-drain valve installed inside the filter cartridge.  This anti-drain valve is a rubber flap that allows oil to flow one direction only (from the outside to the inside).  This valve is standard on most filter cartridge, however if you are not sure consult your supplier or the manufacture.
7.  The final step of installation is to route the hoses away from any sharp or extremely hot objects and install swivel hose ends to the 37-degree flare fittings located on the inlet ports of the adapter and filter-head.  Make sure the hoses do not bend more than what is allowed. Over bending a hose may result in the hoses collapsing and will cause restriction of oil flow.  Fill the filter cartridge with oil and install to the filter-head.
8.  Run the engine, check for any oil leaks, and check oil pressure.  Shut off engine and check oil level, and add if necessary.
