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. 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.
