The document describes the GAS & GO Two-Way Fuel Filter, Model JDI-FF25, an owner's manual detailing its assembly, operation, and maintenance. This device is designed for filtering fuel and is capable of operating in two directions, allowing for both drawing fuel from a source and filling a gas caddy while filtering.

Function Description

The GAS & GO Two-Way Fuel Filter, Model JDI-FF25, serves as a portable fuel filtration system. Its primary function is to filter various types of fuel, including unleaded gasoline, diesel/kerosene, and E85 ethanol, to remove impurities. The "Two-Way" aspect indicates its ability to filter fuel regardless of the direction of flow, meaning it can filter fuel as it is drawn from a source (e.g., a vehicle's fuel tank) or as it is used to fill another container (e.g., a gas caddy). This dual functionality enhances its versatility for fuel transfer and purification tasks. The system incorporates a hand-operated pump to facilitate fuel transfer and filtration.

Important Technical Specifications

While specific flow rates or pressure ratings are not explicitly detailed, the manual provides crucial information regarding the replacement filters and the tools required for assembly and maintenance.

Tools Required for Assembly & Operation:

• 1-1/16" Open End Wrench
• 1-1/4" Open End Wrench
• Phillips Screwdriver
• PTFE Tape (for sealing hose fittings)
• 10 mm Wrench
• 5 mm Hex Wrench

Replacement Filters: The manual specifies different filter types based on the fuel being filtered, each with a corresponding micron rating and part number:

• Unleaded Gasoline: 10 micron (Part No. 10M-FF)
• Diesel/Kerosene: 30 micron (Part No. 30M-FF)
• E85 Ethanol: 1 micron (Part No. 1M-FF)

This indicates that the device is adaptable to various fuel types by simply changing the filter cartridge, ensuring optimal filtration for each specific fuel. The varying micron ratings suggest a tailored approach to filtration, with E85 ethanol requiring the finest filtration (1 micron) and diesel/kerosene requiring a coarser filtration (30 micron).

Usage Features

The GAS & GO Two-Way Fuel Filter is designed for user-friendly operation with several key features:

• Two-Way Filtration: As its name suggests, the filter operates in both directions. When the pump handle is rotated clockwise, it draws fuel from the gas caddy. When rotated counter-clockwise, it facilitates suction. In both scenarios, the fuel is automatically filtered. This eliminates the need to reconfigure the system for different transfer directions.
• Manual Pump Operation: The device utilizes a hand-operated pump. To obtain an initial prime, the pump handle must be rotated briskly. This manual operation makes the device independent of external power sources, enhancing its portability and usability in various environments.
• Grounding Capability: An important safety feature is the green ground wire clamp, which must be attached to a known ground on the vehicle being serviced. This helps prevent static electricity buildup during fuel transfer, reducing the risk of fire or explosion.
• Versatile Fuel Transfer: The device can be used to draw fuel from a source (e.g., a vehicle's tank) or to fill a gas caddy. When filling a gas caddy, the Filler/Vent Assembly can be opened.
• Overfill Prevention: Users are explicitly warned not to overfill the gas caddy. The fuel level must remain below the flame arrestor screen located under the Filler/Vent Assembly, a critical safety measure to prevent fuel spills and potential hazards.
• Hose Connections: The system uses 3/4" NPT hose fittings, which require PTFE tape for proper sealing during assembly. This standard fitting size allows for compatibility with common hoses.

Maintenance Features

Maintenance of the JDI-FF25 primarily revolves around filter replacement and proper sealing:

• Filter Replacement: The manual provides clear instructions and part numbers for replacing filters based on the fuel type. This is a routine maintenance task essential for maintaining filtration efficiency.
• O-Ring Seal Maintenance: When installing a new filter, the O-ring seal should be lubricated with oil or grease before assembly. It should be hand-tightened, then turned approximately 1/2 turn after the rubber seal contacts the filter support. The manual explicitly warns against over-tightening, which could damage the seal.
• Hose Fitting Sealing: All 3/4" NPT hose fittings must be wrapped with PTFE tape during assembly to ensure a leak-free connection. This is a crucial step for both initial setup and any reassembly after maintenance.
• Handle Removal: The pump handle can be removed for maintenance or storage using 10mm and 5mm hex wrenches, indicating a modular design that facilitates access to internal components if needed.
• Bracket Assembly: The filter support bracket assembly may require loosening bolts for initial assembly, but these should be tightened securely afterward.

In summary, the GAS & GO Two-Way Fuel Filter, Model JDI-FF25, is a robust, manually operated, and versatile fuel filtration system designed for safe and efficient fuel transfer and purification across various fuel types. Its two-way filtering capability, ease of filter replacement, and emphasis on safety features like grounding and overfill prevention make it a practical tool for fuel management.
