How A Dedicated Fuel System Functions

As we mentioned earlier, the dedicated fuel system delivers a dose of high octane fuel directly into the nitrous system’s fuel solenoid. Introducing the fuel at the same time the nitrous is flowing is vital to ensure there aren’t any issues in the combustion chamber. Nitrous Outlet has made getting the system online an easy task with how it has everything wired up.

“Basically the way we wire them up is that we wire the pump relay to the arm switch for the nitrous system; this causes the pump to kick on as soon as the nitrous system is armed to make sure you have everything pressurized. This way there’s no delay when the nitrous starts to flow…the nitrous system is getting all of the high-grade fuel directly from the fuel tank with consistent pressure,” McDonald says.



Part of what makes the entire system work so well is the Aeromotive fuel pressure regulator that is attached to the fuel cell. Tuning the fuel pressure via a spring is how you can use different jets in your nitrous system. To make this easier Nitrous Outlet offers both high and lower pressure spring options with the dedicated fuel system.

“There’s a couple of bolts on the regulator that you can remove to take it apart and add either the high- or low-pressure spring. Low pressure is around 10-12 psi, and high pressure is up to around 65 psi. Most of your EFI cars are a high-pressure system from the factory, so to keep your tuning simple you would just keep the high-pressure spring in there and follow the jet chart,” McDonald explains.
