Upgrade the weak factory lift pump on your 1999–2007 7.3L or 6.0L Powerstroke with the FASS TSF14180F140G Titanium Signature Series 140GPH fuel system, engineered for clean, consistent fuel delivery up to 700 HP. This system improves injector life, filters fuel to 2 microns, removes air and water, and runs quieter thanks to FASS Whisper Technology.
140GPH lift pump for 1999–2007 Ford F-250/F-350 7.3L & 6.0L Powerstroke (stock–700 HP).
Preset 60–65 PSI fuel pressure for strong, stable rail supply.
2-micron filtration, air/vapor and water separation for maximum injector protection.
FASS Whisper Technology for noticeably quieter operation.
Mass Flow Return “polishes” fuel by continually circulating and cleaning it.
Bolt-on mounting bracket and PTFE pickup tube for easier installation and tank depth adjustment.
Supports cold-weather performance with optional heater ports.
Limited lifetime warranty and 1,000,000-mile motor life expectancy when installed per FASS guidelines.
The TSF14180F140G Titanium Signature Series is a complete replacement fuel system designed to correct the aerated, poorly filtered fuel supply that kills injectors on 7.3L and 6.0L Powerstroke trucks. Flowing 140 gallons per hour at a preset 60–65 PSI, it supports stock trucks and builds up to roughly 700 HP, making it ideal for tuned, towed, or workhorse rigs that demand consistent fuel delivery.
FASS combines 2-micron filtration, an integrated water separator, and patented air/vapor separation to remove the contaminants and entrained air that factory systems allow through. Cleaner, de-aerated fuel helps stabilize injection timing, reduce injector stiction and wear, and can improve throttle response and mileage in real-world use. Mass Flow Return continually circulates excess fuel back to the tank after filtration, so your truck is constantly running on “polished” fuel instead of whatever is sitting in the tank.
The Titanium Signature Series uses FASS Whisper Technology, which was developed specifically to quiet pump noise while increasing flow, making this one of the quietest high-output diesel lift pumps available. A heavy-duty motor, performance radius-cut fittings, and a robust bolt-on bracket reduce restriction and vibration, contributing to a motor life expectancy of up to 1,000,000 miles when properly installed. The included PTFE pickup tube can be trimmed to tank depth and allows safe operation down to about 1/8 tank when installed correctly.
1999–2007 Ford F-250 & F-350, 7.3L and 6.0L Powerstroke diesel.
Replaces previous part number TS F14 140G (superseded by TSF14180F140G).
Cab & chassis applications may require minor plumbing or mounting modifications.
Helps prevent costly injector failures by removing air, water, and fine particulates.
Supports higher HP tunes, towing, and performance use without starvation.
Quieter cabin and idle compared to many aftermarket lift pumps.
Can improve start-up quality, throttle response, and fuel economy depending on vehicle condition and setup.
Designed and backed by a leading diesel fuel system manufacturer with very low pump failure rates.
FASS backs the Titanium Signature Series with a limited lifetime warranty when installed per their instructions and used with proper filtration and fuel quality. Warranty coverage requires registration, proof of purchase, and installation that follows FASS guidelines (including using approved filters and recommended service intervals). Labor, misuse, contamination, and improper installation are excluded, so professional installation is strongly recommended.
Common signs your factory lift pump or fuel supply system may be failing and could benefit from an upgrade like this FASS system include:
Low fuel pressure or erratic pressure readings, sometimes setting “low fuel pressure” or “fuel delivery” related DTCs depending on monitoring setup.
Hard starting, extended crank time, or intermittent no-start when hot.
Surging, hesitation, or loss of power under load or at higher RPM.
Repeated injector failures, rough idle, or excessive smoke caused by aerated/contaminated fuel.
Noticeable pump noise from the factory unit or signs of fuel cavitation in the filter.
Q: What pressure is this system set at?
A: The Titanium Signature system for 99–07 Powerstroke is preset to approximately 60–65 PSI to properly support HEUI injectors.
Q: How much power will this 140GPH pump support?
A: It is rated to support up to about 700 HP worth of fuel demand on 7.3L and 6.0L Powerstroke engines.
Q: Is this just a lift pump or a full fuel system?
A: It is a complete fuel system that includes a high-flow pump, filters, water/air separation, and a return-style Mass Flow Return design that continually polishes your fuel.
Q: Will it fit a cab & chassis truck?
A: Yes, but cab and chassis models may require minor mounting or plumbing modifications compared to standard pickup tanks.
Q: How noisy is the pump?
A: FASS Whisper Technology significantly reduces operating noise, making this one of the quieter aftermarket diesel lift pumps on the market.
Q: How often should I change the filters?
A: Follow FASS’s recommended filter service intervals or shorten the interval if you operate in dirty-fuel environments or see restricted-fuel symptoms. Typical interval is 30-60k miles.
