Ecotune 1.8TSI High Pressure Fuel Pump Upgrade

Ecotune 1.8TSI High Pressure Fuel Pump Upgrade

1.8TSI HPFP Upgrade Kit with MK7 Golf R Pump | Essential Fuelling Solution for EA888.3 Cars over 370 HP 1.8TSIHPFP

The 1.8TSI High Pressure Fuel Pump (HPFP) Upgrade is the definitive fueling solution for those who are serious about pushing their 1.8TSI EA888.3 engine past the stock limits. Specifically engineered to address the inherent fuel supply limitations of the factory HPFP of the 1.8TSI, this kit is essential for performance upgrades targeting power outputs beyond 370bhp. It ensures the Direct Injection (DI) system can maintain the necessary pressure and flow, preventing the dreaded "fuel cut" that plagues high-power, Stage 3-plus setups.

This product is a High Pressure Fuel Pump upgrade used to significantly increase the fuel flow capacity of the VAG 1.8TSI EA888.3 engine. It is a critical component in performance upgrades, specifically required when higher boost levels and larger turbochargers (like IS38 or hybrid units) demand more fuel than the OEM HPFP can deliver. Upgrading your HPFP to the Golf R HPFP is perfect for Ecotune to integrate seamlessly with their Stage 3 ECU calibrations, ensuring stable, controlled fuel pressure under high-load, high-RPM conditions.

At Moorfield German Motors, we have installed the 1.8TSI HPFP Upgrade on numerous Polo GTI 6C and Ibiza Cupra 6P builds, and the results are consistently fantastic. For the discerning enthusiast looking to push beyond the typical Stage 2 power, this pump is non-negotiable. What we especially appreciate is the full-kit approach. Everything you need to upgrade to the larger-capacity MK7 Golf R pump body and necessary supporting components like the correct Vacuum Pump and a fresh Cam Follower. This saves time and ensures maximum reliability, which is paramount when squeezing over 370bhp from a four-pot engine. 

1. Professional Installation is Highly Recommended: The HPFP is a mechanical, precision-tolerance component driven off the camshaft. Incorrect fitting, particularly poor sealing or damage to the cam follower or pump piston, will lead to immediate, catastrophic engine damage. Installation additionally available for at our MGM HQ

2. ECU Calibration is Essential: This is not a "bolt-on and forget" part. It must be installed in conjunction with an ECU recalibration (tune) that is specifically written to control and utilise the increased flow capacity of the upgraded pump.

3. Best Used in Conjunction with Supporting Mods: To maximise the benefit and hit the 370+bhp target, the HPFP is best paired with a high-flow downpipe, a performance air intake system, and an upgraded intercooler. For extreme power or E85 usage, an Ecotune Low-Pressure Fuel Pump (LPFP) upgrade is also required.

Specification

FAQs for 1.8TSIHPFP

Q: How much extra BHP am I likely to gain from this product?

A: The HPFP itself doesn't directly add power, but it enables significant gains; it is the bottleneck remover that allows your turbo and ECU tune to safely reach outputs over 370bhp.

Q: What is the main purpose of upgrading the High-Pressure Fuel Pump?

A: Its main purpose is to increase the volume of high-pressure fuel delivered to the engine's injectors, preventing the fuel pressure from dropping under the high load demands of a performance remap.

Q: Can I install this HPFP upgrade without an ECU remap?

A: No, an ECU recalibration (tune) is absolutely essential to correctly control the new pump and fuel delivery; running it without a map will cause the car to run poorly or go into limp mode.10

Q: Is the Ecotune HPFP a complete pump replacement or just internals?

A: The kit is comprehensive, complete assembly replacement, often utilising an uprated Golf R pump and all necessary ancillary components for a robust, direct swap.

Q: What are the risks of using the stock HPFP with a Stage 3 tune?

A: The primary risk is a fuel cut, where the stock pump cannot supply enough fuel, leading to a sudden loss of power or, more seriously, running lean which can cause catastrophic engine damage.

Q: Is it safe to use this on my daily-driven Polo GTI?

A: Yes, it is safe, provided it is installed correctly by professionals and the car has a stable, matching ECU calibration; Ecotune products are designed for reliability as well as performance.

Q: What other upgrades should I fit alongside this HPFP?

A: For maximum performance, pair it with a turbo upgrade (like an IS38 hybrid), an upgraded intercooler for cooler air charge, and a high-flow downpipe/exhaust system.

Q: Does this kit come with a new cam follower?

A: Yes, the Ecotune kit typically includes a brand-new, genuine Cam Follower, which is a critical component that should always be replaced during a new HPFP installation.
