Aeromotive VaporWorx ReturnX return-type PWM controllers have everything needed to provide a standalone fuel pump speed control system. Available for single or dual pump, naturally aspirated or supercharged applications, no switches, relays, or Hobb's switches are needed when using these ReturnX systems. Controllers have primary and secondary output with the primary providing sufficient pump speed to maintain fuel pressure during idle/cruise while the secondary pump follows at a lower duty cycle. This leader/follower arrangement delivers a smooth ramp-up in pump speed until both pumps are at full output. For carbureted and EFI applications, simply attach the supplied standalone MAP sensor hose to a manifold vacuum source (naturally aspirated) or past the supercharger/turbocharger and make at-idle controller adjustments--the VaporWorx controller will do the rest. Select the single or dual naturally aspirated or supercharged version needed for your setup. Key features: * Works with all brushed-type fuel pumps * Typical power reduction to the pump(s) of 45 to 75 percent * Standalone MAP-based fuel pump speed control * Carburetor and EFI capability Benefits: * Everything needed electrically to drive the fuel pump(s) * A significant reduction in the average fuel pump power requirement resulting in lower fuel temperatures and longer pump life * 40 to 80-amp minimum continuous power rating in a compact controller package * Over-temperature shutdown with automatic reset will operate indefinitely without damage * Short circuit output protection will operate indefinitely without damage * OEM Delphi/Aptiv connections for terminals, seals, and connector bodies * All cross-linked polyethylene wiring * UL94 rated components used throughout * Integrates into the OE ECM to allow all safety systems to remain functional * 10 to 22 V operating range -- Can be used with voltage boosters -- Lower than 10 V applied to the turn-on circuit will cause controller shutdown to protect from an AFR lean condition

Aeromotive VaporWorx BoostWorx returnless PWM kits for Ford GT have everything needed to provide a standalone, manifold referenced, OE-type returnless fuel system. When used with the low-cost Ford/Motorcraft PFS1215 fuel module, the systems will provide a 42 to 60 psi base pressure with a 1:1 manifold referenced fuel pressure change for up to 25 psi of boost--just like a mechanical fuel pressure regulator would with the ECM tuned in the same manner. The system's key to simplicity is the standalone manifold pressure sensor that tells the BoostWorx controller how to adjust the fuel pressure. Simply connect the hose from the pressure sensor mount to the intake manifold, set the fuel pressure according to the need, and you're done. The controllers can also be used with any engine that needs to have a separate MAP sensor for manifold referenced fuel pressure, and they can be used in constant pressure mode by removing the vacuum line or MAP sensor wiring, and the controller will provide a constant pressure. BoostWorx GT controllers feature: * Everything needed electrically to drive the fuel pump module--no relays, external regulators, or return lines are required * Unmatched low fuel level capability when combined with the OEM-style fuel module * A minimum 50 percent reduction in power to the fuel pump during idle and cruise vs. traditional systems * 40-amp minimum continuous power rating in a compact controller package * Over-temperature shutdown with automatic reset * Short circuit protection that will operate indefinitely without damage * OEM Delphi/Aptiv connections for terminals, seals, and connector bodies * All cross-linked polyethylene wiring * UL94 rated components used throughout * Integrates into the OE ECM to allow all safety systems to remain functional * 10 to 22 V operating capacity -- Can be used with voltage boosters -- Lower than 10 V applied to the turn on circuit will cause controller shutdown to protect from an AFR lean condition * Billet aluminum VaporWorx MAP sensor bracket and 3bar pressure sensor

FASS Fuel Systems D-MAX fuel pump kits enhance your diesel truck's performance. Installing an aftermarket diesel fuel lift pump can be good--greater performance and economy gains--but you may also introduce air and vapor into your fuel when the factory CP3 injection pump pulls fuel under vacuum, and that's bad. FASS D-Max flow enhancers deliver the good without the bad. First, they provide your Duramax engine with a constant 8 psi fuel pressure. This aids the injection system by reducing the CP3's workload, extending its expected life and performance. And second, since the D-Max lift pumps are "pusher" pumps, all fuel is placed under pressure, helping to prevent the introduction of air and vapor. FASS Fuel Systems D-MAX fuel pump kits are the "good" alternatives for your diesel rig and your wallet.

Standard Motor fuel pressure regulators ensure that your vehicle's fuel supply is precisely metered for optimum mileage and performance. Defective fuel pressure regulators most often develop excessive pressures that create an overly rich air/fuel mixture, robbing mileage and performance. Similarly, if the pressure regulator diaphragm leaks through its vacuum hose into the engine intake manifold, the fuel mixture will also become extremely rich. Don't take chances with your fuel supply—rely on Standard Motor Products for your vehicle's fuel system needs. Order the replacement regulator designed for your application.
