S197S Dual Pump Module / Returnless

Electronic returnless configured fuel pump module. Fully upgradeable to operation in a return fuel system.
E85 and race fuel compatible (see pump manufacturer recommendations on fuel compatibility)
Accepts OEM level sender from '07-'12 GT500 only
Viton o-ring pump seals totally eliminate in-tank fuel hose failures.
Deletes restrictive PPRV for highest performance and consistent output
Polymer pump support eliminates pump body electrolysis and minimizes noise
Hermetic wire seal completely eliminates the chance for leaks/smell
* You MUST upgrade the FPDM and electrical system to properly support these upgraded pumps. Suggest dual drivers for best results. Consult with your tuner before selecting pumps.

FAQ:

Can 405 lph (TI F90000262) or 465 lph (TI F90000267) 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 F10000302 (265lph) 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.
