Stainless Steel Oil Filter Bypass Eliminator - BBC Gen 4 and SBC

This strong stainless steel mount does not have a bypass so it eliminates the possibility of unfiltered oil entering the engine while replacing the weak and often failed factory unit.

When a marine engine is installed in the bilge of a boat there is little or no access to the bottom of the engine therefore a remote mounted oil filter is required.  An oil filter block off adapter must be bolted on the original oil filter location to accomplish this.  These block off adapters are constructed of stainless steel.  They are completely O-ringed on the sealing surfaces to eliminate oil leaks, copper sealing washers are NOT used under the mounting bolt heads.

HP4 Oil Filter Screen

These high flow stainless steel oil filter screens were designed to provide fast easy access engine oiling system inspection. Each high quality stainless steel screen sandwiches between the engine oil filter and filter head. Simply spin off your oil filter provides easy access to the filter screen.
