Perko 1324 Fuel System Locking Cap, For 1-1/2 in Non-Vented Fills

Overview

The Perko 1324 is a fuel system locking cap for 1-1/2" non-vented fills, used as a replacement cap on compatible Perko deck fills. It is made from black polymer with a gasket, and it has a built-in lock cylinder with a cover over the key hole to help keep the fuel fill closed off when the boat is unattended.

This cap is meant for pre-EPA fuel fill applications and should be matched by both fill series and cap outside thread diameter before ordering. The two available fit sizes cover different Perko fill models, with outside thread diameters of 1-15/32" or 1-7/8" depending on the variant.

Key features

• Made for 1-1/2" non-vented fuel fills on compatible Perko deck fills.
• Black polymer cap with a gasket to help maintain the seal at the fuel fill opening.
• Built-in lock cylinder with a cover for the key hole to limit access to the fuel fill cap.
• Two fit sizes cover specific Perko fill families, so the cap can be matched to the existing deck fill rather than selected by appearance alone.
• Cannot be keyed alike, which keeps each cap keyed separately for security.
• For pre-EPA use only, so it should be checked against the vessel’s existing fuel fill and emissions setup before replacement.

Variants

This fuel system locking cap is offered in two configurations, each tied to a specific Perko fill fitment group and cap outside thread diameter.

Both variants use black polymer construction with a gasket and a built-in lock cylinder with a key hole cover. The fit size, compatible Perko fill numbers, and outside thread diameter are the key differences to confirm before ordering.

• 1324DP0BLK: Locking Cap Black, Size #0, for Perko fills 1313 and 1399, with a 1-15/32" outside thread diameter. This version suits boats using those listed Perko non-vented fills and should be matched to the existing cap thread size.
• 1324DP1BLK: Locking Cap Chrome, Size #1, for Perko fills 0520, 0527, 0528, 0557, 0599, and 1270, with a 1-7/8" outside thread diameter. This version fits the larger listed Perko fill group and is the correct match when the existing fill uses the Size #1 cap thread.

Compatibility and fit

Fuel fill caps are fit-sensitive parts. Before replacing a missing or worn cap, confirm the Perko fill number on the boat or compare the existing cap thread diameter to the variant information above. A cap that looks similar may not seal or thread correctly if the fill series or thread diameter is different.

Use on board

This locking cap is a practical replacement for boats kept at marinas, on trailers, or in shared storage areas where the fuel fill needs a simple lockable closure. It is also useful during refits when the original Perko cap is missing, worn, or no longer locking properly, as long as the deck fill and pre-EPA application match the cap specification.
