Volvo Penta 3860590 is a genuine OEM hose used in Volvo Penta gasoline-engine cooling and fuel-system service. The strongest current public application trail places it in the freshwater cooling parts listing for V8-300-A and V8-320-A engines, where it is identified as item 22 and specifically tied to the fuel pump area. Current Volvo dealer-style catalog pages also label this part simply as a Volvo Penta hose and show the same fuel pump application note.
Key Features
- Genuine Volvo Penta OEM hose, part number 3860590.
- Strongest current public fitment trail places it in freshwater cooling service on Volvo Penta V8-300-A and V8-320-A applications.
- Current Volvo parts references associate this hose with the fuel pump position.
- One current public listing shows approximate weight around 0.19 lb (0.086 kg).
Engine Compatibility
The strongest supportable fitment trail for Volvo Penta 3860590 is with V8-300-A and V8-320-A gasoline applications in the freshwater cooling parts layout, where the hose is connected to the fuel pump callout. Because the public references are much clearer on the assembly area than on a broad official model-family list, the safest fitment standard is the exact Volvo Penta serial-number-based parts diagram for the engine being serviced.
Serial Number Fitment Notice
Fitment can vary by engine package, cooling layout, and hose routing. Confirm Volvo Penta part number 3860590 against your engine serial number and the correct Volvo Penta parts diagram before ordering, especially on gasoline engines where several nearby molded hoses can look similar once removed.
When This Part Needs Replacement
Replace this hose when the original hose shows swelling, cracking, soft spots, clamp-area wear, seepage, abrasion, or age-related hardening. It is also a smart replacement during adjacent cooling-system or fuel-pump-area service if the original hose has already been disturbed or shows visible wear.
Installation Notes
Match this hose to the exact Volvo Penta application before installation. The strongest public references place it in the freshwater cooling layout at the fuel pump position, so confirming both the part number and exact diagram location is the safest cross-check before ordering or reassembly. Inspect the related clamps and adjoining hose connections at the same time to help avoid repeat leaks after service.
Alternate/Superseded Part Numbers
Use Volvo Penta 3860590 as the primary ordering number. In the current public sources reviewed, no stronger confirmed Volvo supersession trail was found beyond the active number itself.
Parts Desk Insight
Hoses around the fuel-pump and cooling layout are easy to mis-order because nearby hoses can look close once they are off the engine. Matching the exact Volvo Penta diagram position first is usually much safer than comparing bends and diameter by eye alone.
