1542114 Pressure Pipe | Genuine Volvo Penta Part

🔧 Product Description

This is a genuine Volvo Penta high-pressure fuel pipe from the fuel system group, machined specifically for cylinder number 4. It carries pressurised fuel from the injection pump to that cylinder's injector, and because each pipe in the set is shaped and routed for one cylinder position, this item is not interchangeable with the pipes for cylinders 1, 2 or 3. It suits the 40-series marine diesel engines, including MD40A, TMD40 and TAMD40 variants.

🔌 Function

The pressure pipe delivers metered fuel at high injection pressure from the injection pump outlet to the injector of cylinder 4. Its fixed length and bend geometry maintain correct injection timing and volume for that cylinder.

⚠️ Common Signs of Failure

• Fuel weeping or spraying at the union nuts at either end of the pipe
• Rough running, misfire or power loss traced to one cylinder
• Hard starting or extended cranking caused by loss of injection pressure
• Visible cracks, chafing, corrosion or kinks along the pipe body
• Flared sealing cones damaged or distorted after repeated removal, preventing a leak-free seal

🛠️ Service Notes

• Cap or plug both ends and keep the pipe and its unions scrupulously clean until the moment it goes on — a pressure line is no place for grit
• Offer the pipe up unstressed: start both unions by hand and let the pipe find its own line before anything is tightened down
• Never bend, straighten or reshape a pressure pipe to make it fit, and never dress or file a sealing cone; a pipe with a damaged or distorted seat is scrap
• Tighten the unions to the figures and sequence in the workshop manual for your engine, and renew rather than refit any pipe the manual treats as a single-use part
• Refit every clip and support bracket so vibration is not carried on the unions, then run up and check for weeps at working pressure, keeping hands well clear of any high-pressure fuel joint
