1547951 Sealing Ring | Genuine Volvo Penta Part

🔧 Product Description

This genuine Volvo Penta sealing ring is a formed OEM sealing component used in the fuel-pump sealing. It is manufactured to the original Volvo Penta dimensions and interface requirements so the mating joint retains its intended fluid, gas or contamination barrier. In service, it seals the fuel-pump mounting interface to prevent oil or fuel leakage and maintain correct pump installation. Fitment is controlled by the exact engine or product configuration and serialised parts list; confirm OEM number 1547951 against the installed assembly before ordering.

🚤 Compatibility

• Engine Family: D, TWD, TAD
• HP Range: Approximately 521 HP

🔌 Function

Seals the fuel-pump mounting interface to prevent oil or fuel leakage and maintain correct pump installation. Clean the groove and mating faces, confirm the seal material and installed orientation, and inspect the completed joint under normal operating pressure.

⚠️ Common Signs of Failure

• Visible fuel weeping, seepage or wet residue around the sealed joint
• Fuel odour in the engine compartment
• Hard starting, rough running or power loss caused by air drawn into the fuel system
• Hardened, flattened, cracked or deformed ring on inspection
• Loss of fuel pressure or repeated need to re-tighten the connection

🛠️ Service Notes

• Always fit a new sealing ring rather than reusing the old one — a ring that has been compressed once has taken a set and will not seal reliably a second time
• Clean the groove or seat and check it for scoring, corrosion and old sealant before fitting; a mark across the sealing face will leak however good the ring is
• Ease the ring into place without stretching, twisting or dragging it over sharp edges or threads, and check it is seated squarely all the way round before closing the joint
• Do not add sealant or jointing compound unless the workshop manual for your engine calls for it, and tighten the joint or union to the figure given in that manual
• Check the joint for weeping once the engine has been run up to temperature and allowed to cool, as many sealing rings only show a leak after a heat cycle
