Sometimes the best thing you can do is step away for a few days and spend time with the people who matter most. ❤️🏖️

A lot of you know what it’s taken to build Weldon’s Diesel Performance from the ground up. Running a small business means long days, late nights, and wearing just about every hat there is. I wouldn’t trade it for anything—but it’s also easy to let time with family slip by.

This summer, our kids have spent countless days at the shop, helping out, washing trucks, and making sure to drive their dad crazy. It’s the adults turn to unwind while the kiddos run wild!

We’ll be taking a short family vacation to the beach to recharge and celebrate everything this past year has brought us.

📅 The shop will be CLOSED Thursday, July 30th, through Tuesday, August 4th, and we’ll REOPEN Wednesday, August 5th.

Thank you to every customer, friend, and family member who has supported us along the way. Your trust in us means more than you know.

We’ll see y’all next week—rested, refreshed, and ready to keep your diesel on the road. 🇺🇸🔧

🛠️ LET’S TALK SHOP: THE CP4 FUEL PUMP 🛠️

If you own a newer diesel, especially a 6.7 Power Stroke, this is something you need to understand.

The CP4 high-pressure fuel pump is responsible for creating the extreme fuel pressure your injectors need to deliver power and efficiency.

So why does everyone talk about the CP4?

Because when these pumps fail, they don’t always fail quietly…

A CP4 can experience internal wear and begin creating metal contamination that travels throughout the entire fuel system.

That means a failed pump can take out:
🔧 Fuel injectors
🔧 Fuel rails
🔧 High-pressure fuel lines
🔧 The entire fuel system

What started as one failed component can quickly become a repair bill costing thousands.

So what’s the fix?

The first step many owners take is the S&S Diesel Motorsport Disaster Prevention Kit.

A Disaster Prevention Kit is designed to help protect your fuel system by catching and managing contamination if a CP4 failure occurs — helping prevent a single failure from becoming a complete fuel system disaster.

But if you’re looking for the ultimate solution…

🔥 S&S Diesel Motorsport DCR Conversion 🔥

The DCR Conversion replaces the CP4 with a more robust fuel pump solution designed to eliminate the factory CP4 concern altogether.

Think of it like this:

✅ Disaster Prevention Kit = Protect your truck if the CP4 fails
✅ DCR Conversion = Remove the CP4 weak point and upgrade the system

You can have the best parts money can buy…

✔️ DCR Conversion
✔️ Fuel system upgrades
✔️ Performance parts

But if your truck has bad tuning, none of it matters.

We recently had a truck come in with low fuel rail pressure codes. After upgrading the entire fuel system with a DCR conversion, it still wouldn’t go over 50 MPH. No warning lights. No codes. Nothing.

The problem?

The tuning.

As soon as we replaced the questionable tune with quality calibration, the truck came alive and drove exactly like it should.

The lesson: Don’t just ask what tune you’re getting—ask who’s behind it.

The wrong tune can cost you time, money, performance, and even damage expensive components. Quality tuning isn’t just about making horsepower. It’s about making your truck run the way it was meant to.

At Weldon’s Diesel Performance, we believe your tune should match the quality of the parts you’re investing in.

Nobody posts the parts that fight back… but they should. 😂

This 2020 Power Stroke was in the shop for a fuel system upgrade when an injector hold-down bolt decided it wasn’t leaving without a fight.

We got it extracted cleanly, avoided unnecessary damage, and kept the job pushing.

If you’re thinking about upgrading your Power Stroke, let us handle the headaches… You just enjoy the results. 🔥🔧

The Heart of Every Diesel Starts with Maintenance. 🛠️

Performance upgrades are exciting, but routine maintenance is what keeps your diesel running strong for the long haul.

From oil changes and fuel filters to cooling system service, transmission maintenance, and complete inspections, staying ahead of maintenance is the key to avoiding costly repairs and unexpected downtime.

Whether you rely on your truck for work, towing, or everyday driving, we’re here to help keep it dependable for miles to come.

School’s out… but the shop definitely isn’t! 😂

If there’s anyone who understands having the kiddos home 24/7, it’s a busy diesel mechanic. Around here, summer break just means it’s “Bring Your Kid to Work” season. From pressure washing trucks to “helping” under the lift, they’re making sure Dad stays on his toes. 😅

Life gets busy, family comes first, and honestly, we wouldn’t have it any other way.

While they’re keeping us entertained, we’re still doing what we do best—getting your diesel repaired, upgraded, and back on the road.

Thanks for trusting our family with your truck. We appreciate every one of you. ❤️🛻🔧
