Diesel Injector Leak Off Pipe Assembly for Massey Ferguson 35 & 100 Series Tractors

Description

When you start smelling diesel around your Massey 35 or notice that telltale drip of fuel under the engine, there’s a good chance this leak off pipe is calling it quits. This small but critical component carries excess fuel from your injectors back to the tank safely, and when it cracks or hardens with age, you’re looking at wasted fuel, fire hazards, and fuel fumes in the cab. Time to get that fuel system sealed up tight again.

What You’re Getting

• Fuel-resistant material that handles modern diesel fuels without degrading or cracking
• Precisely sized internal diameter maintains proper fuel flow without creating back pressure
• All connection points engineered to seal properly without over-tightening
• Complete assembly ready to install – no cutting or adapting needed
• Includes the fitting kit (QTP-62696) for a complete repair

Built for Real Farm Work

Your Massey Ferguson 35 or 35X diesel is the go-to tractor for countless small farms – perfect for running a hay tedder, pulling a small disc, operating a loader, or powering a rotary cutter. This leak off pipe also fits the 100 series models like the 133 and 135. When this pipe fails, you’re not just losing expensive diesel fuel – you’re creating fire hazards and potentially damaging injector performance, plus dealing with the smell of diesel in the cab during long working days.

Made to Last

This isn’t just any fuel hose – it’s specifically designed for the fuel injection system’s leak off circuit, with materials that resist the degrading effects of modern diesel fuels while maintaining flexibility in both summer heat and winter cold. The internal diameter is precisely sized to maintain proper fuel flow without creating back pressure that could affect injector performance.

Installation Notes

Replacing a leak off pipe is straightforward but requires attention to safety – always work with a cold engine and have a fire extinguisher nearby when working with fuel systems. The leak off pipe typically connects to each injector with small banjo fittings or push-on connections, then routes back to the fuel tank return. Don’t force connections – they should fit snugly but not require excessive force, then run the engine and check for leaks before putting the tractor back to work.
