Every 6.5L owner knows the feeling.

You're pulling a trailer, climbing a hill, and your eyes keep drifting to the temperature gauge.

The DieselSite SuperCool Water Pump Upgrade Kit was built to end that anxiety. Featuring a proprietary high-performance water pump, heavy-duty fan clutch, oversized 9-blade fan, thermostat, radiator cap, and installation hardware, it's one of the most effective upgrades you can make for a hard-working 6.5L.

Keep your cool—no matter what's behind the hitch.

Your injection pump is expensive. Your fuel filter shouldn't be the weak link.

The DieselSite 6.5L Remote Fuel Filter Kit adds an extra layer of defense to your fuel system by filtering out contaminants and separating water before they can reach your injection pump. Working alongside the factory filter, it uses a high-efficiency Baldwin water-coalescing filter to help safeguard the components that keep your 6.5L running strong.

Especially when installing a replacement injection pump, this is the kind of upgrade that can help prevent costly fuel system damage caused by poor fuel quality.

Clean fuel. Protected components. More miles.

The truck shown is also equipped with the DieselSite Coolant Filtration System, helping protect the cooling system from contaminants for even greater long-term reliability.

Ask any 7.3L builder—replacing a damaged timing cover isn't a job anyone looks forward to.

DieselSite's LPOP Repair Kit was engineered to eliminate that headache. Instead of replacing the entire cover, simply install the precision-ground wear plate to restore the oil pump surface with a durable, serviceable repair. If the surface is ever damaged again, replacing the wear plate is far easier—and far less expensive—than replacing the timing cover.

It's the kind of simple, innovative solution that saves hours of labor while helping your engine maintain efficient oil pump performance.

When a smarter repair is available, why replace the whole timing cover?

Still running a mechanical fuel pump?

Take the next step with confidence.

The DIESELSITE Fuel Pump Control Module is designed to make upgrading from a mechanical fuel pump to an electric fuel pump quick, simple, and reliable. With intelligent microprocessor control, it primes the pump at key-on, runs it only when the engine has oil pressure, and automatically shuts it off if oil pressure is lost for added safety.

⚡ Easy electric fuel pump conversion
🛡️ Automatic safety shutoff
🔧 Simple installation
🇺🇸 Proudly made in the USA

Make the switch the right way—with the controller built to protect your fuel system and keep your engine running strong.

Still fighting valve cover leaks?

It's probably not your gasket.

The factory stamped steel valve covers on the GM 6.2L and 6.5L diesel are notorious for flexing, making it difficult to get a consistent seal.

That's why DIESELSITE developed its Valve Cover Plate & Stud Kit.

The heavy-duty stainless steel hold-down plates distribute clamping force evenly, while the stud kit makes installation easier and helps keep everything aligned.

✔ Better seal
✔ Easier installation
✔ Built to last

Stop replacing gaskets.

Start fixing the problem.

Your 7.3L isn’t done. It’s just getting started. 💪🔥

No gimmicks. No shortcuts. Just a proven upgrade for one of the most legendary diesel engines ever built.
