Removing Filters
WARNING
Servicing filters without shutting off power properly and ensuring that the appropriate
valves are closed may result in fuel discharge or spray. Any involved STPs with power still
applied can be energized from another unit resulting in fuel pressure in the product lines
for the unit you are working on. Pumping units with power applied could also be accidently
energized. Commonly, retightening of the filter under pressure will not stop fuel flow as the
seal can be blown out of the sealing position during tightening.
Fire and explosion could result in severe injury or death.
Ensure the following:
• Wear eye protection
• Test and close the involved shear valves
• Shut off power to the pump, dispensers, and any involved STPs
• Remove parts slowly. Collect fuel in approved containers.
• Clean up all spills promptly
Use an approved container to collect the residual fuel. Use gasoline/fuel-approved absorbent
materials to mop up the spilled fuel. Use Gasboy-approved fuel collectors, if applicable. Be
careful of any residual fuel. Always follow all safety warnings and cautions.
To remove filters, proceed as follows:
1
Slowly turn the filter counterclockwise. Use a filter wrench if necessary, to loosen the filter.
2
Drain the removed filter into an approved container and dispose of properly. Do not dispose of
filters and fuel soaked absorbent materials in trash cans. Follow local, state, and national code
requirements for disposal. Use of a fuel catch-cup or pan is recommended.
3
Remove the strainer and clean. See
