🚨 LML DURAMAX OWNERS — KNOW THIS BEFORE IT COSTS YOU THOUSANDS 🚨

If your truck still has the factory CP4 injection pump, this is something you NEED to understand.

The CP4 is known to fail — and when it does, it doesn’t just quit… it self-destructs.

When that pump goes:
💥 It sends metal shavings through your entire fuel system
💥 Injectors, rails, lines, tank — ALL contaminated
💥 You’re no longer fixing a pump… you’re replacing the whole system

That’s exactly what you’re seeing in these photos — metal contamination throughout the fuel system. This is a full teardown and clean-out situation.

⚠️ Most failures happen with little to no warning
⚠️ One bad tank of fuel or low lubrication can speed it up
⚠️ Repair bills can easily hit $8K–$12K+

👉 The good news: this can be PREVENTED.

We recommend:
✔️ CP4 → CP3 conversion
✔️ Proper filtration upgrades
✔️ Quality fuel practices

At Dirty Diamond Diesel in Mooreland, Indiana, we deal with this ALL the time. Whether you’re trying to prevent failure or already dealing with contamination, we’ve got you covered.
