8 PORT FITTING
1. This filter is supplied with a 40 micron pleated stainless 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 frequent the filter disc must be cleaned.
5. In most cases, the filter disc can be cleaned and reused 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.
