Overview
The Perko 0582DPS99A is a replacement cap for Perko 0582 and 0583 style vented deck fills used on 1-1/2" fill hose systems. It includes gas, diesel, and water inserts, and it is meant for traditional non-EPA vented fill arrangements rather than EPA compliant sealed fuel systems.
This cap is a practical service part when the original cap is worn, missing, or no longer clearly marked at the deck fill. The polished stainless steel cap has a scalloped shape that is easy to grip by hand, and the retaining cable helps keep the cap attached to the fill instead of ending up loose on deck or overboard.
Key features
- Fits Perko 0582 and 0583 style vented deck fills
- Polished stainless steel cap with a scalloped hand-grip profile
- Includes interchangeable inserts for gas, diesel, and water identification
- Polymer retaining cable helps keep the cap with the fill assembly
- Made for non-EPA vented fill setups and not for EPA compliant sealed fuel systems
- Sold as a single replacement cap assembly
Compatibility and fit
This replacement cap is intended for Perko 0582 angled-neck and 0583 straight-neck vented fills. Those fill bodies are commonly used with 1-1/2" fill hose, so this part is a good match when the existing fill remains in service and only the cap needs replacement.
It is not a universal cap for every deck fill, and it should not be used on sealed EPA fuel systems. On older boats with separate deck fills for fuel or water, matching the cap style matters because the cap needs to suit the fill body already installed on the deck.
Installation and setup
Replacement is straightforward: remove the worn cap, check that the fill neck and sealing surface are clean, and fit the new cap with the correct insert for the tank below. Clear labeling at the fill point matters on a busy fuel dock, especially on boats that carry both fuel and water fills in the same area.
This is a sensible replacement for center consoles, cruising boats, and sailboats that still use Perko vented fills and need the original cap style back in place without changing the full deck fill assembly.
