CP4 Let You Down? Alliant Power's Contamination Kits to the Rescue!
When it comes to maintaining your 6.7L Power Stroke, fuel system contamination is one of the worst nightmares a diesel owner can face. A single tank of bad fuel or water intrusion can wreak havoc on your fuel system, leading to costly repairs and significant downtime.
Fortunately, Alliant Power offers high-quality Fuel Contamination Kits for 2011-2022 Ford 6.7L Power Stroke engines to help you get back on the road quickly and reliably.
Why Is Fuel Contamination a Big Deal?
The modern 6.7L Power Stroke is engineered for high performance and efficiency, but it operates under extreme pressure, reaching up to 36,000 PSI in the fuel system. Even the smallest amount of contamination, whether from water, debris, or improper fuel, can cause catastrophic damage to components like the high-pressure fuel pump (HPFP), injectors, and fuel rails.
Common causes of contamination:
Water Intrusion
Poor-quality fuel or condensation
DEF Contamination
Accidental misfueling with diesel exhaust fluid
Metal Shavings
Debris from a failed CP4 / HPFP
Dirt & Debris
Contaminants entering the fuel tank
