These hoses can handle the extreme exposure that heavy usages puts upon them

thereby increasing pump reliability

In the event of one pump failing the electronic controller will automatically switch all fuel delivery responsibilities to the remaining operational pump

This kit will not produce more fuel pressure than the engine ECU requests

Adequate fuel flow is vital to producing maximum efficient/clean horsepower

Fluorocarbon lining offers better lubricity (slippery and resistant to chemicals) and the silicone rubber construction ensures they can withstand constant boost pressures and temperatures from 76 degrees all the way to +437 degrees Fahrenheit. PPE silicone will maintain structural integrity even when subject to high boost pressures
