Preaux Tuning 21+ F150 5.0L Fuel Rail and Line Kit

Designed for those 21+ F150 5.0L forced induction guys who want to eliminate the limiting factory fuel rail setup.

The factory rail setup places the fuel rail pressure at the tail end of the bank 2 port side rail, which is furthest from the crossover to port transition, which on high power ethanol setups can cause that sensor to see a reduction in pressure due to the location and limitations of fuel getting to the sensor. This can skew the fuel demand sent to the lift pump causing the pump to work overtime to satisfy a potentially false fuel demand.

Not only does this setup look killer but its intent was pure performance based to allow proper tuning to extract as much power as possible from both the direct injection and port injection systems.

The kit includes all of the fittings needed to connect to existing lines, rails, spacers, and line support brackets.
