21159427 Hollow Screw | Genuine Volvo Penta Part

🔧 Product Description

A genuine Volvo Penta cross-drilled banjo bolt used in the TAD1345GE low-pressure fuel and breather arrangement. Fuel passes through its axial and radial drilling while the screw clamps the banjo eye between two sealing rings, making bore size and sealing-shoulder geometry part of the fuel-system calibration.

🚤 Compatibility

• Engine Family: TAD, TWD, D

⚙️ Key Features

• Cross-drilled banjo screw for diesel-fuel service
• Internal passage sized for the specified low-pressure circuit
• Machined sealing faces match the original sealing rings
• High-strength body maintains clamp load without distorting the banjo fitting
• Confirmed on the TAD1345GE fuel system from SN2013227625-
• Engine type: 13-litre electronically controlled generator diesel low-pressure fuel system

🔌 Function

Secures the banjo fitting and simultaneously provides a sealed internal passage for fuel flow.

⚠️ Common Signs of Failure

• Unstable idle, misfire or reduced power
• Fuel leakage or air ingress
• Injection or fuel-pressure fault codes
• Excessive smoke, combustion knock or uneven exhaust temperature

🛠️ Service Notes

• Check the through-passage is clear and clean before fitting; a blocked hollow screw starves whatever it feeds
• Always fit new sealing washers, one each side of the union where the original had them, and never reuse a crushed washer
• Hold the fitting or pipe end against turning as you tighten, so the line is not twisted and the union is not pulled out of position
• Tighten to the figure in the workshop manual for your engine — these seal by crushing the washer, not by force, and over-tightening splits the head or shears the shank
• Bring the system up to working pressure and check for weeps before closing the space up
