21163590 Suction Pipe | Genuine Volvo Penta Part

🔧 Product Description

A formed oil-pickup pipe that reaches from the D3 oil pump into the sump. Its inlet depth and orientation keep the pickup submerged during acceleration, trim changes and vessel movement, while its large bore limits suction restriction.

🔌 Function

Draws engine oil from the sump and delivers it to the oil-pump inlet with minimal restriction.

⚠️ Common Signs of Failure

• Low or fluctuating oil pressure, worst on acceleration or in a seaway
• Oil pressure warning flickering when the boat is trimmed or heeled
• Aerated, foamy oil on the dipstick
• Rattle or whine from the oil pump as it draws air
• Cracked pipe, split seam or a blocked pickup screen found when the sump is dropped

🛠️ Service Notes

• Renew the O-ring at the pump connection whenever the pipe is removed
• Check the sump for debris and the pickup for blockage before fitting, as a restricted pickup and a failing pump give the same symptoms
• This pipe supersedes 3588212, so confirm the pickup depth suits the fitted oil pan
