Ecotune MQB Fuel Line Upgrade
The OEM fuel system on the EA888.3 platform presents several restrictions, all of which are addressed by this Ecotune fuel line upgrade. This enhancement not only boasts a 25% increase in line bore diameter but also significantly improves fuel delivery and reduces fuel pump controller duty.
These lines are designed for easy installation, improving flow from any original location Low Pressure Fuel Pump (LPFP). You’ll see substantial benefits, even when coupled with the OEM pump.
Ecotune’s lines are manufactured from stainless steel braided nitrile hose, with a nylon overbraid for maximum durability. A combination of black aluminum AN-6 fittings and high-flow quick connectors forms a top-quality kit that offers excellent value.
Two Options for Seamless Integration:
Ecotune offers two distinct options to perfectly suit your setup:
- OEM HPFP Fitment: This option is designed for vehicles utilizing the OEM High Pressure Fuel Pump (HPFP), including those with upgraded internals.
- Ecotune HPFP Fitment: This option is specifically tailored for seamless connection to the Ecotune HPFP via an AN-6 fitting.
What’s Included in the Kit:
The Ecotune Fuel Line Upgrade kit comprises two key components:
- Engine Bay Upgrade: This replaces the fuel lines running from the bulkhead to feed both the Multi-Port Injection (MPI) rail and the HPFP. It includes a join over the inlet manifold, allowing for the easy incorporation of a FlexFuel sensor (not required, but can be added).
- Tank to Engine Bay Upgrade: This component replaces the fuel line directly from the cap of the LPFP and connects to the engine line upgrade at the FlexFuel sensor split.
