Summit Racing™ introduces its MAX-efi 500 Fuel Injector System, the most efficient way to convert your carbureted engine to premier EFI performance. These self-tuning throttle body units bolt directly to most 4-barrel manifolds; then, through their wideband oxygen sensor, the systems continually adjust fuel delivery to provide the optimum air/fuel ratio under all climate and altitude conditions. MAX-efi will support up to 500 hp, and the self-learning ECU allows for easy tuning. With safety in mind, these systems are also designed with a self-adjusting "limp home" mode to protect your engine if a sensor fails. In addition, they include a data-logging feature to track the system while it's running to ensure optimal performance. Other features of the Summit Racing™ MAX-efi 500 Fuel Injector Systems: * Powered by the most advanced self-learning technology available * 4-injector system is capable of supporting stock to 500 hp engines * High-flow aluminum throttle body with four 45mm diameter throttle bores * OE-quality wideband 02 sensor and TPS sensor included * Color touch screen hand-held controller * Billet aluminum anodized fuel rails * Compact external ECU for easy mounting * OE-style harness is clearly marked for easy installation and durability in extreme conditions * All sensors except the wideband 02 sensor and coolant temp sensor are integrated on the unit * Uses commonly available sensors for easy replacement if necessary * System uses a Temperature Manifold Absolute Pressure (TMAP) sensor instead of a MAP sensor, reading both air pressure and temperature * Fits square bore or spread bore intake manifolds. (Spread bore manifold requires an inexpensive plate to avoid leaks. See SUM-G1420) * Works with original carb-type distributor, factory-style throttle linkage, and most 4-barrel intake manifolds

Hybrid Racing K-Swap fuel rails are made from 6061 aluminum with T6 heat treatment—and feature a durable anodized finish with a laser-etched logo, ensuring that your engine bay looks fresh and your engine stays fed! Each rail includes a 1/8 in. NPT hole that allows you to mount a fuel pressure gauge directly to your fuel rail. This puts the fuel pressure gauge in a spot that's easily visible, so you don't have to poke around in the engine bay just to see if you have fuel pressure. All of the ports can accept a -8 ORB fitting in the inlet(s) and outlet, enabling you to run either -6 or -8 AN fuel lines. The other detail that should stand out is the option for plugging the side inlet and outlet to allow you to run your fuel line to a centrally located -8 ORB fitting. This is positioned so that the fuel line can pass between the middle two cylinder intake runners (depending on your intake manifold.) This is an excellent option for anyone looking to tuck their wires and lines. Additional notes: * These rails have been shown to mount to the PRB, RBC, and RBB intake manifolds without needing any modifications. Any aftermarket intake manifolds that share the same fuel rail mounting points as the PRB, RBC, or RBB should also accept this rail. * Available with a Dust Red or Dust Black finish * E85 compatible * What's included: -- (1) K-Series fuel rail -- (2) -8 ORB / -6 AN adapter fitting -- (2) -8 ORB plug -- (1) 1/8th NPT plug

Insufficient pressure from the relief valve spring leads to diagnostic trouble codes you'd rather not see. Pacific Performance Engineering race fuel valve O-rings combine with the stainless steel valve itself to maintain fuel rail pressure during heavy engine load conditions. They block the pressure relief port completely, preventing fuel return to the tank. These Viton® O-rings are made from chemical-resistant rubber--better quality than the OEM O-ring for a longer part life. Eliminate potential low fuel rail pressure DTC codes P1093 and P0087 during power enrichment, courtesy of Pacific Performance Engineering race fuel valve O-rings.
