SRO Fuel Rail Filter and Splitter for V6/8/10/12/16 Engines.

Modern V layout engines tend to use returnless fuel systems and single feed lines. This ends up causing an effective length for the fuel rail of at least double that of either side of the engine. This ends up delivering significantly lower pressure to the last few cylinders of the engine and promoting lean conditions and blown cylinders and engines.

It's an easy and fairly inexpensive thing to fix. You just have to supply fuel to both rails from a common source with similar overall line lengths. This will give you a much more capable fuel system using your stock pump and injectors without letting it get too lean. Of course you MUST still select the proper fuel pump and injector specs for your power level but at least the fuel lines won't cause you a huge problem.

Here are some pics of the core of the unit. This picks up fuel from the cars hard line and delivers it to two billet fuel rails. There's also a place on the pictured model for a fuel temperature sensor. We can use a standard Aeroquip Y fitting if you don't need the temperature probe.
