thereby increasing pump reliability

It is extremely crucial to keep the oil as clean as possible from even the smallest dirt particles that circulate through the engine and wear away internal components

With time and exposure

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

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
