- Does NOT include fuel pumps. Select option to include Fuel Pumps above.
- Wiring upgrade not required for under 525 rwhp
- Do not use with pre 1999 ECU
Simple and cost effective pump upgrade. High performance Walbro (TI Automotive) fuel pumps can be calibrated to work seamlessly the original PWM fuel pump control system. Upgraded electrical system and upgraded Fuel Pump Driver Module (FPDM) is not included and may be required.
- Retains factory returnless configuration
- Non intrusive installation
Includes:
- SN95 Fuel Pump Module (dual pump)
- OEM Feed Line Adapter Kit
- O-ring plug for return port
- High current Delphi connector with 7' pigtail of 12 AWG wire
FAQ:
Can 405 lph or 465 lph pumps be operated in a returnless configuration?
No, the pumps' minimum output is too much supply for idle/cruising. (two pumps) We do not recommend running anything larger than the F90000265 (305lph) fuel pumps in this configuration.
Do you sell upgraded FPDMs?
No, a second Fuel Pump Driver Module (FPDM) and pigtail harness can be purchased from Ford. Some of our customers use our FC2 controller as a power supply for twin FPDMs.
How much power can be made in a PWM (returnless) configuration?
We have supported over 1000 rwhp in a PWM configuration, but we generally set the limit around 700-750 rwhp (gasoline applications, lower for E85) for driveability. Due to the fact that "electronic returnless" is a reactive fuel system (it is always a step behind the motor demand) it generally cannot adequately keep up with the severe demand transients that modified motor requires.
