🔧 Product Description

Genuine high-pressure injector pipe used on cylinders 4, 5 and 6 of Volvo Penta TAD750GE and TAD751GE common-rail diesel engines. Each pipe must remain in the specified cylinder position and must not be reshaped.

🚤 Compatibility

Typically suits:

• Volvo Penta TAD750GE
• Volvo Penta TAD751GE

• Engine Family: TAD

⚙️ Key Features

• TAD750GE/TAD751GE high-pressure injector pipe
• Used at cylinders 4, 5 and 6
• Precision sealing cones and factory bend profile
• Designed for common-rail injection pressure
• Three pipes used in the documented six-cylinder arrangement
• 3 used per assembly

🔌 Function

The pipe transfers high-pressure diesel fuel from the common rail to injectors 4, 5 or 6.

⚠️ Common Signs of Failure

• Fuel leakage or mist
• Rail-pressure loss
• Pipe cracking from incorrect support or bending
• Fuel-system derate

🛠️ 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
