Overview

The AMS Performance VR30DDTT Stage 4 High Pressure Fuel Pump (ALP.28.07.0001) is the top pump in AMS's VR30 lineup, built for max-effort ALPHA 8+ packages and the fuel volume needed for 700+ whp on E85. It fits the 2016-2024 Infiniti Q50 3.0t, 2017-2022 Q60 3.0t and 2023-2027 Nissan Z.

It uses a 12mm piston, the largest in the AMS range, and AMS rates it at 440 LPH, the highest flowing pump on the market for this engine. The internal flow paths were optimized with computational fluid dynamics, the pump runs at up to 250 bar, and the body is all stainless steel with laser welded construction for leak-free sealing. AMS developed it with Nostrum High Performance, and it is fully E85 and flex fuel compatible.

Every pump arrives fully assembled and individually flow tested, with OEM-style and AN fuel fittings, an OEM-type harness adapter, a gas line shaping tool and the mounting hardware. Choose the low pressure feed line option if your car does not already have an AMS Flex Fuel Kit.

Before You Order

An ECU calibration is required. The engine will start and run with the pump installed, but a qualified calibrator must review datalogs and adjust the tune. Cars without an AMS Flex Fuel Kit need a -6AN low pressure feed line; choose "Yes" above to add it.

Installation

AMS's Stage 1-4 HPFP installation guide (PDF) covers the physical install. AMS includes a separate calibration quick-start guide for your tuner. AMS states that the pump must be installed and removed only by a qualified motorsport technician trained on this vehicle.

FAQ

Stage 2 or Stage 4?
The AMS Stage 2 High Pressure Fuel Pump suits most bolt-on and mid-level builds. The Stage 4 is for ALPHA 8+ and 700+ whp E85 builds.

Do I need the low pressure feed line?
Only if your car does not have an AMS Flex Fuel Kit. AMS flex fuel cars already have the right feed. Everyone else needs the -6AN line, either from the "Yes" option or custom made.

Do I need a tune?
Yes. The pump needs calibration changes and a datalog review by a qualified tuner.
