Volvo Penta Anti-Siphon Fitting 828501

Volvo Penta 828501 is a genuine fitting used in Volvo Penta’s vacuum valve / anti-siphon assembly. Volvo Penta’s official parts catalog identifies 828501 as a branch pipe, while current replacement-market references commonly describe it as part of the vacuum kit or anti-siphon setup. That makes anti-siphon fitting a solid customer-facing description, with branch pipe being the official Volvo Penta naming.

Engine Compatibility
Current public sources reviewed confirm 828501 as a Volvo Penta branch pipe used in the vacuum valve / anti-siphon system, but they do not provide a dependable model-by-model fitment list in the visible source text. The safest fitment method is to confirm part number 828501 against your exact engine or drive serial number and the correct Volvo Penta schematic before ordering. Volvo Penta specifically advises identifying the engine, shield, or drive when selecting genuine parts.

Serial Number Fitment Notice
Anti-siphon and vacuum-valve components can vary by installation, hose layout, and production break. Confirm Volvo Penta 828501 by serial number and assembly diagram before ordering to make sure you get the correct fitting for your exact setup.

When This Part Needs Replacement
Replace this fitting when the original part is cracked, corroded, leaking, blocked, or damaged during vacuum valve / anti-siphon service. It is also worth replacing when rebuilding the full assembly if the surrounding valve components are already apart.

Installation Notes
Match the part by serial number and the correct vacuum-valve schematic before installation. Inspect the connected hose, mating surfaces, and surrounding anti-siphon components so the full assembly can seal and vent correctly after service. Current parts references place 828501 alongside other vacuum-valve service pieces and the repair kit for that assembly.

Alternate/Superseded Part Numbers
Current sources reviewed identify 828501 as the key Volvo Penta ordering number for this fitting. One current marketplace listing notes that it is associated with vacuum kit 21662704, but the cleanest ordering reference remains Volvo Penta 828501.

Parts Desk Insight
This is the kind of small fitting that is easy to overlook in an anti-siphon system, but it can hold up a repair when the valve assembly is already apart. For older Volvo Penta installations, it is smart to verify the whole vacuum-valve layout at the same time, because the fitting, gaskets, and valve sections all work together to prevent unwanted water movement through the system.
