830898 Mariner SEAL, Oil

Do not allow dirt to enter the fuel system. Thoroughly clean the area around a fuel system component that will be disconnected. Fit a suitable cover over disconnected fuel system component.
Care must be taken to ensure that fluids are contained during performance of inspection, maintenance, testing, adjusting and repair of the product. Be prepared to collect the fluid with suitable containers before opening any compartment or disassembling any component containing fluids.Dispose of all fluids according to local regulations and mandates.
Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
Note: Place identification marks on all hoses for installation purposes. Plug all hoses and all the ports in the fuel filter base. Plugging hoses and ports helps prevent fluid loss, and plugging hoses and ports helps to keep contaminants from entering the fuel system.
