Description
When your diesel fuel injector starts weeping fuel or you’re noticing diesel stains around the injector, it’s usually this little washer that’s given up. Whether you’re running a Ford 4000, Massey Ferguson 165, or any other diesel tractor with a DPA pump, fuel leaks aren’t just wasteful – they’re dangerous around hot engines and can leave you stranded if the pump loses prime. This precision-sized injector washer creates the critical seal between your injector and the cylinder head, keeping fuel where it belongs and your tractor running clean.
Key Features
- Proper 9/16″ x 13/16″ dimensions for exact fit on your Massey’s fuel system
- Made from fuel-resistant materials that handle diesel exposure and engine heat
- Creates a leak-proof seal under high injection pressures
- Direct replacement for worn or damaged original washers
- TISCO quality construction built for farm duty
Built for Real Farm Work
The Ferguson TEF20, often called the “Little Grey Fergie,” revolutionized farming in the 1940s and 50s with Harry Ferguson’s three-point hitch system. The Massey Ferguson 35, nicknamed “Gold Belly” for its distinctive gold-painted engine, became one of the most popular tractors ever built. These are the dependable workhorses that power small farms, hay operations, and custom work like brush hogging and property maintenance. When you’re counting on your diesel to fire up for morning chores or harvest season, a properly sealed fuel injector is essential.
Made to Last
This washer is manufactured to withstand the constant pressure cycling and chemical exposure that comes with diesel injection systems. Injector pipes take incredible abuse – they handle extreme fuel pressures thousands of times per minute while dealing with engine vibration and heat. The same goes for these washers—they need to seal tight under pressure while resisting diesel fuel and staying flexible through temperature changes.
Installation Notes
Replace these washers whenever you remove an injector for service or testing. The old washer often sticks to either the injector or cylinder head—clean both surfaces thoroughly before installing the new one. Don’t reuse old washers even if they look good—the compression set from years of use means they won’t seal properly. Torque your injector to spec after installation to ensure proper sealing without over-stressing the washer.
