Installation
We recommend that additional filtration should be considered as the primary filter and installed before the
factory filter, which should be retained as originally fitted. It can also be installed as a final filter. Identify a
suitable location to mount the filter assembly that:
• The filter head should be securely fixed
vertically to a chassis rail, bulkhead or mounting
bracket using two suitable 1/4”-20 UNC machine
screws or bolts, ensuring they insert a maximum
of 10mm into the threaded mounting holes.
• Install the threaded fuel line fittings into the
head, noting the direction of flow marked on
the head assembly. Use a fuel resistant thread
sealant to ensure a leak free seal. Tighten firmly
with a suitable tool. Do not over tighten!
• Run the fuel supply line (from the fuel tank) and
fit onto the inlet side of the filter head fuel fitting.
Secure with a suitable hose clamp.
• Run the fuel feed line (to the engine) and
connect to the outlet side of the filter head
assembly. Secure with a suitable hose clamp.
• Check there are no tight bends or kinks in the
fuel lines, and route them away from heat
sources and sharp surfaces. Secure fuel lines to
prevent excessive movement.
• Allows access to replace the filter
• Allows access to the twist and drain valve, to
drain separated water
• Provides visibility of the clear water
collection bowl
• Is located away from heat sources
