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.

Part #3176: 40 micron (for use as a pump pre-filter

or to protect carbs)

Part #3177: 5 micron (to protect fuel injectors)
