FASS Fuel Systems 140gph/60psi Series Adjustable Fuel Pump FAS F15 140G 99-07 Ford F250 F350 Powerstroke

Boost 99-07 Powerstroke Fuel System Performance

Many 7.3L and 6.0L Powerstroke owners face common fuel system issues. The factory fuel pump often struggles to maintain consistent pressure. This is especially true under heavy load, when towing, or with performance tunes installed. Low fuel pressure can starve your injectors, lead to poor atomization, and shorten the lifespan of expensive engine components.

The FASS Fuel Systems 140gph/60psi Series Adjustable Fuel Pump, model FAS F15 140G, solves these problems directly. It provides a reliable, consistent fuel supply to your 1999-2007 Ford F-250 or F-350 Powerstroke. This isn't just about more power. It's about protecting your engine and getting the most out of your diesel.

FASS F15 140G Powerstroke Fuel Pump Overview

The FASS F15 140G is a complete fuel air separation system. It replaces your truck's restrictive factory fuel pump and filter setup. This unit draws fuel from the tank, filters it, removes air and vapor, and delivers it to your engine at a stable 60 PSI.

This pump is built for diesel performance. It ensures your injectors always receive clean, air-free fuel at the correct pressure. This improves combustion efficiency and extends injector life. The 140 gallons per hour (GPH) flow rate supports stock and moderately modified Powerstroke engines.

At CI Motorsports, we've seen firsthand the difference a properly functioning fuel system makes. Upgrading to a FASS system is a common recommendation for Powerstroke reliability and performance.

Key Features of the FASS F15 140G

This FASS fuel pump offers specific benefits for your Powerstroke:

• 140 Gallons Per Hour (GPH) Flow Rate: Provides ample fuel for stock to moderately upgraded engines.
• Adjustable 60 PSI Fuel Pressure: Maintains consistent, optimal fuel pressure for injectors. This is critical for preventing injector damage.
• Fuel Air Separation System: Removes entrained air and vapor from your diesel fuel. Air in the fuel system can cause reduced power, rough idling, and premature wear on injectors.
• Advanced Fuel Filtration: Integrated filters remove harmful contaminants from your fuel. This protects your expensive injector system and engine.
• Premium Construction: Built with durable materials to withstand harsh operating conditions and provide long-term reliability.
• Direct Fitment: Designed for a straightforward installation on specific 1999-2007 Ford F-250 and F-350 Powerstroke models. It integrates with your existing fuel lines and wiring.
• Manufacturer Warranty: Comes with FASS Fuel Systems' warranty for peace of mind.

Installation Notes

Installing the FASS F15 140G pump requires mechanical skill and specific tools. Here's what you need to know:

Tools Required:

• Standard metric and SAE wrench sets
• Socket set
• Fuel line disconnect tools
• Torque wrench
• Jack and jack stands or a lift (recommended for easier access)
• Wire cutters/strippers, crimpers
• Drill (for mounting hardware)

Time Estimate:

Expect 4-6 hours for an experienced technician. A capable DIY mechanic should plan for 6-8 hours. Rushing the process can lead to mistakes.

Difficulty:

Moderate to advanced. This is not a beginner-level installation. It involves working with the fuel system, electrical components, and under the vehicle.

Common Mistakes to Avoid:

• Improper Fuel Line Connections: Ensure all fittings are tight and sealed. Leaks can cause dangerous fuel spills and system malfunctions. Double-check all O-rings and gaskets.
• Incorrect Wiring: Follow the wiring diagram exactly. Improper wiring can damage the pump or vehicle electronics. Always disconnect the battery before starting electrical work.
• Not Priming the System: After installation, the fuel system must be properly primed to remove air. Failing to do so can prevent the engine from starting or damage the new pump.
• Skipping Filter Pre-Fill: Pre-fill new fuel filters with clean diesel before installation. This helps with priming and prevents dry starts.
• Improper Mounting: The pump needs to be securely mounted to the frame. Ensure it's clear of moving parts and protected from road debris.

Professional installation is always recommended for fuel system components. This ensures proper function and safety.

Always confirm your vehicle's specific engine and trim level. If you have any doubts, contact our team with your VIN before ordering.

Maintenance and Care

Keeping your FASS system running efficiently is straightforward. Regular maintenance ensures continued performance and protection for your engine.

• Filter Changes: Adhere to FASS's recommended filter change intervals. This is typically every 15,000 to 30,000 miles, but check your manual or local fuel quality. Neglecting filter changes reduces filtration efficiency and can strain the pump.
• Inspect Lines and Connections: Periodically check all fuel lines, connections, and fittings for signs of wear, chafing, or leaks. Address any issues promptly.
• Monitor Fuel Pressure: If you have an in-cab fuel pressure gauge, monitor it regularly. A drop in pressure could indicate a clogged filter, a pump issue, or a leak.

Proper maintenance extends the life of your FASS pump and your Powerstroke engine.
