Station Layout Site Preparation
3 – Site Preparation
IMPORTANT INFORMATION
When preparing the site, use safety tape, cones, or barricades to block the work area.
Station Layout
Recommended guidelines for the Station Layout are as follows:
• Consider traffic flow, kiosk, and store location when planning location of pumps/dispensers.
• Plan islands for efficient routing of plumbing and wiring. Arrange product lines by hose
and foundation layouts (refer to MDE-4331 Atlas Fuel Systems Installation Manual).
Follow local codes.
Note: Actual flow rates will depend on your specific installation and accessories used.
Remember pipe size and number of fittings can affect flow rate. Refer to
Considerations for DEF Dispensers” on page 26.
• Place pumps/dispensers such that the customers can dispense fuel safely and conveniently.
• Install pumps/dispensers at least 8-feet apart on island.
• Consider the service person who must have easy access to the entire pump/dispenser (top,
rear, front, and sides). Gasboy recommends at least 60 inches of clearance from any
structure (for example, wall, fence).
• Install protective posts at ends of island to protect pumps/dispensers against collision.
Posts must not interfere with customer fueling.
“Important
Product System Layout
• Distance from tank to pump must not be more than 50-feet.
• Fuel line dimensions, refer to “Pipe Size” on page 30.
• Fuel line minimum burial depth starting at inlet riser to the pumping unit is 18 inches.
• Fuel line piping sloping rate of 1-1/2 to 2 inches per 10-feet of piping run.
Note: Traps and sags are not acceptable.
• Avoid unnecessary elbows and/or turns in piping. Each elbow and turn decreases product
flow and if used in excess may cause issues with fuel delivery.
• Maximum lift is 10-feet (refer to “Fuel Tanks” on page 29).
• Pumps (self contained units) must have a vacuum actuated pressure regulating valve to
prevent positive pressure at the pump base when used with aboveground tanks.
• For aboveground tank installations, refer to “Shear Valves” on page 31 and
“Pipe Installation” on page 29.
