1542115 Delivery Pipe | Genuine Volvo Penta Part

🔧 Product Description

This is a genuine Volvo Penta fuel delivery pipe from the fuel system group, carrying pressurised fuel between the injection pump and its connection point on the engine. This particular pipe is the version specified for use with part 1542185, so it must be matched to that assembly rather than substituted with another delivery pipe of the same name. It suits the 40-series marine diesel engines, including the MD40A, TMD40 and TAMD40 variants.

🔌 Function

The delivery pipe routes fuel under pressure from the injection pump to its outlet connection, maintaining a sealed, leak-free path within the fuel system. Correct pipe length and fitting match are essential for both sealing integrity and injection timing consistency.

⚠️ Common Signs of Failure

• Visible fuel weeping or staining at the pipe unions or along the pipe body
• Hard starting, misfire or power loss caused by a pressure leak in the fuel line
• Cracked, chafed or fatigued pipe wall from vibration or repeated removal
• Damaged, distorted or over-tightened sealing faces at the nut ends that will not seal
• Corrosion or internal blockage restricting fuel delivery

🛠️ Service Notes

• Work scrupulously clean — cap or plug every opening as it is broken and let nothing enter the pipe or its unions, because a single particle carried into the injection system will damage what it reaches
• Offer the pipe up so the union faces meet squarely and fit it dry and without strain; never bend, straighten or re-form a delivery pipe to make it reach
• Renew rather than reuse a pipe where the procedure for your engine calls for it — the sealing cone work-hardens in service and often will not seal a second time
• Tighten the unions with the correct socket to the figure in the workshop manual for your engine; under-tightening leaks and over-tightening deforms and cracks the sealing cone
• Never slacken a union to bleed or check a system that is running or still pressurised, and look for leaks only with the engine stopped and the area wiped dry
