🚨 6.7L Power Stroke Owners – CP4 Failure Protection Is Here 🚨

If you own a 2011–2025 Ford 6.7L Power Stroke, you already know the CP4 fuel pump is one of the biggest ticking time bombs on these trucks. When it fails, it can send metal through the entire fuel system and turn into a $8,000–$15,000 repair fast.

We offer professional installation of CP4 Disaster Prevention Kits at our shop.

✅ Helps protect injectors, rails, lines, and tank from CP4 debris

✅ Adds a return-side filtration system to catch metal before it spreads

✅ OE-style quick connects, clean install, no hack jobs

✅ Uses high-quality spin-on fuel filter

This kit doesn’t magically fix a bad pump, but it can save your entire fuel system if the CP4 decides to self-destruct.

🔧 Installed by experienced diesel techs

💰 A fraction of the cost of a full fuel system replacement

If you plan on keeping your truck, towing, or relying on it for work, this is cheap insurance.

Hot Shot's Secret EDT+Winter Defense
We use and recommend this stuff because it works:
Prevents fuel gelling
Improves cold starts
Boost fuel lubricity

If your truck struggles when temps drop, this is a cheap insurance against no-start mornings and fuel system headaches. We keep it on hand and can be added to your service or stop by and get a bottle.
