INSTALLATION INSTRUCTIONS
INLINE FUEL FILTER
PART NO. 3175
1. This filter is supplied with a 40 micron pleated stain-
less steel filter disc suitable for use as a pre-filter for
Mallory fule pumps or as a filter to protect carburetors.
2. Fuel flow can be either direction through the filter.
3. This filter may be used to filter gasoline or alcohol or
any other type of petroleum based fuel.
4. Maximum recommended flow is 500 gallons per hour
for a clean filter. The larger the flow, the more fre-
quent the filter disc must be cleaned.
5. In most cases, the filter disc can be cleaned and re-
used indefinitely. To clean the filter disc, back flush
the filter by flowing fuel in the opposite direction of
normal flow into a bucket. This will remove most types
of debris. If the debris refuses to come out, the filter
disc can be replaced.
6. This filter is supplied with a fitting that will screw di-
rectly into the inlet of a Mallory 250, 110FI, or 160FI
pump so that the filter functions as a pre-filter. Alter-
native fittings may be used to mount the filter in other
types/sizes of fuel lines.
7. The o-rings used in this filter are made from Buna-N
(Nitrile).
The plug o-ring is a #2-125.
The port o-rings are standard -10AN size (#3-910)
The fitting o-ring is a standard -8AN size (#3-908)
These o-rings are available at many automotive parts
stores if they need to be replaced. The o-rings are also
included with replacement filter discs available from
Mallory.

or to protect carbs) 500 GPH Max
