AMS Alpha Fuel System Fuel Rail Kit | Lamborghini Huracan / Audi R8

The AMS Performance Alpha Fuel System Fuel Rail Kit (ALP.37.07.0004-1) replaces the port injection fuel rails on the Lamborghini Huracan and Audi R8 V10 with CNC machined, black anodized 6061 T6 billet aluminum rails. Each rail gives you four more ports than stock, so you can plumb the fuel system any way you like: series or parallel, returned or returnless.

AMS confirmed fitment with both the factory intake manifold and the AMS Alpha Intake Manifold. The rails connect with race-grade AN fittings and 2,000+ psi rated PTFE lined hose with a silver heat sheath, and every material is ethanol and methanol compatible. As part of the complete Alpha Fuel System with the triple pump kit, the system supports 3,200+ hp on gasoline and 2,400+ hp on E85.

You can build your own system around these rails or pair them with the AMS Fuel Pressure Regulator + Fuel Line Kit, which AMS designed to match them exactly.

Specifications

Before You Order

Contents follow AMS's product photos. AMS does not publish an itemized list, so call us if you need to confirm a specific fitting before ordering.

The four Alpha Fuel System parts are designed to work together. AMS notes some custom fitting is needed if you are not running the complete system. AMS states that its fuel system parts must be installed and removed only by a qualified motorsport technician trained on this vehicle.

Installation

AMS's R8/Huracan Alpha Fuel System installation guide (PDF) includes the fuel rail kit. AMS splits its R8/Huracan Alpha Fuel System into four parts that are sold separately but designed to work as one system: the Twin or Triple Pump Kit at the tank, the Fuel Pressure Regulator + Fuel Line Kit in the engine bay, the Fuel Rail Kit on the intake manifold, and an optional Flex Fuel Kit add-on. AMS notes that some custom fitting is needed if you are not running the complete Alpha Fuel System.

FAQ

Does it fit the AMS intake manifold?
Yes. AMS confirmed fitment with both the factory intake manifold and the AMS Alpha Billet V10 Intake Manifold.

Can I run a return-style system?
Yes. The extra ports let you plumb the rails in series or parallel, returned or returnless.

What pairs with these rails?
The AMS Alpha Fuel Pressure Regulator + Fuel Line Kit is designed as the perfect match, fed by the AMS Alpha Fuel System Twin Pump Kit or AMS Alpha Fuel System Triple Pump Kit.
