Figure 2.1: Triple Bump Tube and Retaining Pin
2.2 Filter and Strainer Remotes
The filter should be changed and the strainer cleaned on a regular basis. A dirty filter and
strainer may cause the dispenser to deliver fuel slowly. In some cases, this may appear to be a
more serious service related problem, when simply changing the filter and cleaning the strainer
is all that is required.
Before removing the filter, trip the shear valve and turn OFF the circuit breaker for the associated
submersible pump.
On Remote dispensers, the fuel filter is removed the same way an oil filter is removed from a
car engine. For Suction Pumps, see Section 11. As shown in Fig 2.2 for remotes, the new fuel
funnel catches any fuel that is spilled and properly drains it into a container. Place a container
under the funnel spout when changing the filter.
To install the new filter, first apply a film of oil to the gasket and hand turn until the gasket contacts
the base. Then tighten one half turn. Open the emergency shear valve, turn the submersible
circuit breaker ON and check for leaks. In new installations it may be necessary to change the
filter frequently in the first few days of operation in order to ensure proper operation.
The strainer is located inside the casting and held in place by the filter. Place a suitable container
below filter/strainer casting to catch product and sediment. Remove the filter and gently pull the
strainer out of the filter/strainer casting. Clean strainer screen of any debris. Reinstall strainer
and a new filter.
If the underground installation is new, it may be necessary to clean the strainer screen two or
three times the first few days of operation to remove debris and pipe dope. After this, occasional
cleaning of the strainer is all that should be required. The fuel filter should be changed whenever
the strainer is cleaned.
