The 1110010024 Fuel Drain Valve is precision-engineered using high-quality brass forgings that are then CNC-machined to achieve a superior surface finish on both the body and the tapered plug. The sealing interface is lapped to a mirror finish, ensuring a metal-to-metal seal that is complemented by an O-ring for redundant protection. This dual-sealing approach guarantees zero leakage, even after thousands of operation cycles.
The valve’s handle is ergonomically designed with a knurled grip, allowing for easy turning even with oily hands. The internal flow passage is sized to allow rapid drainage without clogging, and the outlet is positioned to direct fluid away from sensitive components. Every 1110010024 is pressure-tested and inspected for thread conformity, ensuring that it meets HOWO’s rigorous quality standards. This meticulous engineering translates into a drain valve that you can rely on for the life of your vehicle.
The 1110010024 is specifically designed for HOWO heavy-duty trucks, including T7H, A7, and other models equipped with MC11 or MC13 engines. It is typically installed at the bottom of the fuel filter/water separator assembly, where it provides a convenient drain point for accumulated water and sediment. Its M18x1.5 thread is standard across many commercial diesel applications, making it a versatile replacement part.
This valve is also compatible with certain Sinotruk and other vehicles that use the same fuel filter housing. To confirm fitment, always check the thread size and the OEM number on your existing valve. If it matches 1110010024, you have the correct replacement. Keeping this valve in your spare parts stock ensures that you can quickly address water-in-fuel issues, preventing injector damage and unscheduled downtime.

Replacing a faulty or leaking drain valve with the 1110010024 delivers immediate improvements in fuel system integrity. A tight seal prevents air from being drawn into the fuel lines, which can cause hard starting, rough idle, and loss of power. Additionally, regular draining of water and sediment using this valve extends the life of the fuel filter and protects the high-pressure pump and injectors from abrasive particles.
The corrosion-resistant brass construction ensures that the valve remains functional even after years of exposure to diesel fuel and moisture. Fleet operators will appreciate the reduction in fuel-related breakdowns and the lower cost of ownership that comes from using genuine OEM components. By investing in the 1110010024, you safeguard your engine’s most sensitive components and maintain peak fuel efficiency.
Installing the 1110010024 Fuel Drain Valve is a straightforward task. Begin by ensuring the fuel system is depressurized (if equipped with a primer pump, operate it to release pressure). Place a suitable container under the valve to catch any residual fuel.
Using a wrench, unscrew the old valve from the filter housing. Clean the threads inside the housing with a thread chaser or a clean cloth to remove debris. Apply a thin layer of thread sealant (compatible with diesel) to the new valve’s threads, taking care not to get sealant on the sealing face. Hand-thread the new valve into the housing, then tighten it to the recommended torque (typically 20-25 Nm) using a torque wrench. Do not overtighten.
After installation, prime the fuel system and check for leaks. Operate the valve a few times to ensure smooth movement and positive shut-off. Periodically inspect the valve for any signs of leakage or corrosion. If the valve becomes difficult to turn, apply a small amount of diesel-compatible lubricant to the stem. With proper care, the 1110010024 will provide years of reliable service.
Pro Tip: Always replace the O-ring seal if it shows any signs of wear or flattening. The O-ring is the primary seal against leakage, and a fresh one ensures a perfect seal. The 1110010024 comes with a new O-ring pre-installed for your convenience.
Genuine HOWO components are engineered to the highest standards, and the 1110010024 Fuel Drain Valve is no exception. Aftermarket valves often use cheaper brass alloys, inferior O-rings, or imprecise threads that can lead to leaks, seizing, or cross-threading. HOWO’s valve is manufactured using the same materials and processes as the original equipment, guaranteeing a perfect fit and reliable performance.
By choosing the 1110010024, you benefit from HOWO’s extensive research and durability testing, which includes exposure to diesel fuels, additives, and extreme temperature cycling. This ensures that the valve maintains its sealing integrity over the long term. Moreover, genuine parts are backed by a comprehensive warranty and supported by a global network, giving you confidence in your purchase.
