AMS Alpha Fuel Pressure Regulator + Fuel Line Kit | Huracan / Audi R8

The AMS Performance Alpha Fuel System Fuel Pressure Regulator + Fuel Line Kit (ALP.37.07.0003-1) is the engine bay link between the Alpha pump kit in the tank and the Alpha fuel rails on the Lamborghini Huracan and Audi R8 V10. It sets up a returnless, deadhead routing to the port injection rails, which keeps fuel pressure steady at the rails at any power level and keeps pressure up after shutdown for fast starts.

Fuel passes through a Fuelab billet aluminum inline filter housing with an integrated check valve and a 6 micron glass element before it reaches the engine. Pressure is set by an Aeromotive extreme flow regulator, read on a 100 psi Marshall gauge. AMS mounts it on a two-piece bracket that sandwiches five rubber isolator bushings to cut vibration and noise into the chassis.

All lines are race-grade, 2,000+ psi rated PTFE lined hose, so no fuel fumes escape into the engine bay or your garage. They use AN and aluminum quick connect fittings with a silver heat sheath, and every material is ethanol and methanol compatible. With the triple pump kit, the full Alpha Fuel System supports 3,200+ hp on gasoline and 2,400+ hp on E85.

Specifications

Before You Order

These items come from AMS's product description and photos. A replacement Fuelab filter (Fuelab part 71804) is available separately.

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. Spyder models can be fitted, but the regulator assembly needs custom mounting. 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 FPR and line 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 Spyder?
Yes, but AMS says the regulator assembly needs custom mounting on Spyder models.

Which pump kit should I pair it with?
Either the AMS Alpha Fuel System Twin Pump Kit or the AMS Alpha Fuel System Triple Pump Kit, with the AMS Alpha Fuel System Fuel Rail Kit on the engine.

Is the filter serviceable?
Yes. The Fuelab housing takes replacement filter part 71804, sold separately.

Fitment Notes

Fits the Gen 2 Audi R8 V10 and the Lamborghini Huracan, coupe and Spyder (Spyder needs custom regulator mounting). Call us to confirm your exact version before ordering. Browse all AMS Performance parts.
