container, where they can propagate rust or
algal formation. Every time the container is
opened, fresh water vapour enters, so the
water level progressively builds up, unless
it’s drained. Also, bungs in upright 200-litre
drums have been known to allow rainwater
that has pooled on the lid of the drum to seep
into the drum, sucked in via the bung threads
by a pressure drop in the drum as it cools at
night. Grit entry into vehicle or machinery fuel
tanks as they’re being filled is an ever-present
risk. Water and grit are fatal to all engines
and, often, the standard filtration system isn’t
up to the job of eradicating them from the fuel
injection system.The funnel blocks the passage of these
contaminants before they can enter the fuel
tank, without the use of an external filter. In
the centre of the Funnel mouth is a fixed,
Teflon-coated stainless steel screen that
readily passes hydrocarbon fuels, but blocks
the passage of water and solids, down to100 microns in size. The Funnel neck is
sized to fit snugly into the restricted tank
opening on unleaded-petrol vehicles and the
polypropylene Funnel material is infused with
carbon, making it anti-static (if an extension
hose is required for hard-to-reach tank necks
it should also be anti-static – preferably
metal).The filter assembly is fixed and maintenance-
free. In fact, even wiping the filter surface
isn’t recommended. Operation of the filter
is easily checked periodically, by filling the
bottom third of the Funnel with water. If the
filter medium is intact the water will not pass
through. Any combustion system additives
should be squirted directly into the engine fuel
tank. The Lubemate Fuel Filter Funnel is an
ideal safety tool for anyone filling engine tanks
from containers or in dusty conditions.Lubemate’s new Universal Clamping Funnel
