FK8/FL5 Civic/DE5 Acura Integra Type S & CV2 Accord Modified High Pressure Line "Service Only" V3

The Best Modified High-Pressure Fuel Line in the game cause our Dyno Graph's say so. Let’s first start with the fact that our modification has a radial taper vs the non-radial tapers the competitors use. To get the most out of your fuel system you will need to upgrade this high-pressure pipe running from the High Pressure Fuel Pump to the Fuel Rail.

10% fuel injector duty reduction can be expected on FK8s with an Upgraded Fuel Systems, which results in additional fuel at the tip of the injector. For Accords and SI platforms we have seen a variance from 6-8% increase on e30/91 Octane.

Extra care is taken to make sure that flow is as high as possible while allowing proper fuel pump control and minimizing fuel pulsation. This includes adding an optimal degreed radial taper at the opening of the fuel line. Each fuel line is drilled and reamed to a specific size with a titanium bit.

This ensures a smooth finish allowing the least restriction while maintaining a size conducive to proper high-pressure fuel pump function. We have tested many designs and sizes to create the best possible result. If you want the most out of your fuel system then look no further.
