About X59407700023 - HP Fuel Line
Published catalog details are identification references. They do not establish current stock, supplied condition, or confirmed fitment for your engine.
X59407700023 is an HP fuel line catalogued for MTU 4000 engines. It is the later number for X00027068, X59407700013, so lists quoting those numbers are normally supplied as X59407700023. The catalog unit weight is 0.285 kg, which we use to estimate freight before quoting.
Technical Notes: Fuel system
The fuel system meters and delivers fuel at the pressure and timing the combustion process needs. Small wear in injectors, pumps, or valves shows up as higher fuel consumption, smoke, uneven cylinder temperatures, or rough running long before a complete failure.
Series 4000 engines use common-rail fuel injection, with high rail pressures and injectors that are sensitive to fuel cleanliness. Fuel filtration and high-pressure line condition deserve particular attention.
When This Type of Part Is Usually Replaced
- exhaust temperatures differ noticeably between cylinders
- black smoke, hard starting, or knocking points to injection problems
- fuel leaks appear at high-pressure lines, unions, or pump seals
Checks Before Ordering
- Check the maintenance documentation on reusing high-pressure lines; deformed sealing cones on refitted lines are a common leak source
- Injectors should be ordered with the correct seals and copper rings for the cylinder head
- Exchange (EX-prefixed) injectors and pumps are a practical option when new units have long lead times
