5840782802 Specification
About 5840782802 - Supply Pipe
Published catalog details are identification references. They do not establish current stock, supplied condition, or confirmed fitment for your engine.
5840782802 is a supply pipe from the HP fuel line group of MTU 956 and MTU 1163 engines. It is the later number for 5840700533, 5840701033, 5840701433, 5840701533, so lists quoting those numbers are normally supplied as 5840782802. The catalog unit weight is 0.681 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 956 engines use conventional injection systems, and many have been in service for decades, so supersession checks are a normal part of quoting fuel-system parts.
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
