Can I Run Dual Fuel Rails?

Put simply, Yes you can run dual fuel rails on a billet intake manifold. If you're building for serious horsepower, it's often the best way to go.

We offer dual fuel rail compatibility across a range of our RB and JZ billet intake manifolds. Whether you're chasing 1000hp+ on the street or pushing your build at the track, a twin-rail setup gives you the flexibility and fuel delivery performance needed to get the most out of your engine. 

Why Run Dual Fuel Rails?

Running dual fuel rails ensures consistent fuel delivery across all cylinders, especially under high boost and RPM. For applications where you're injecting a large volume of fuel or using 12 injectors, a twin-rail setup helps prevent pressure drop and fuel starvation.

Our Billet Manifolds Are Built For It

All CPC billet manifolds are made in-house from 6061 T6 aluminium using CNC precision machining. We design our RB25, RB26, RB30, 1JZ, and 2JZ manifolds to suit single or dual rail configurations. Our kits include the required mounts and stainless hardware, and we support -8AN or -10AN fuel rail options for both setups.

High Power, No Compromise

Whether you're running pump fuel, ethanol, or methanol, dual fuel rails offer peace of mind when tuning for high power. Coupled with our internal bellmouth runners, O-ring sealing, and modular plenum design, our manifolds give you proven performance with race-ready reliability.
