It sits inside the fill neck and adds keyed access without replacing the full deck fill, using a black polymer body with a zinc alloy lock cylinder.\u003c\/p\u003e\u003cp\u003eThis insert is made for compatible Perko vented fills and works with the same key used to open the fill cap, which keeps fueling simple when you are topping off at the dock or fueling from a trailer. It is intended for Perko fill models 0540, 0541, 0580, 0581, 0582, 0583, 0590, 0591, and 1318, and it is not for EPA-compliant gas fills with vacuum pressure relief valves.\u003c\/p\u003e\u003ch6\u003eKey features\u003c\/h6\u003e\u003cul\u003e\n\u003cli\u003eFits most Perko 1-1\/2 inch vented fills, with direct compatibility for models 0540, 0541, 0580, 0581, 0582, 0583, 0590, 0591, and 1318\u003c\/li\u003e\n\u003cli\u003eBlack polymer insert with a zinc alloy lock cylinder\u003c\/li\u003e\n\u003cli\u003eDual-purpose key opens the fill cap and releases the locking insert\u003c\/li\u003e\n\u003cli\u003eRetrofit style insert that works with the existing compatible vented fill instead of replacing the deck fitting\u003c\/li\u003e\n\u003cli\u003eNot for use with Perko EPA-compliant gas fills that use a vacuum pressure relief valve system, including figures 0660, 0661, 0662, 0663, 0780, 0781, 0782, 0783, 0790, and 0791\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch6\u003eCompatibility and fit\u003c\/h6\u003e\u003cp\u003eThis part matters most by fill model, not by boat brand. It is a fit item for Perko vented fuel fills with a 1-1\/2 inch fill size, so it should be checked against the figure number already installed on the deck fill before ordering.\u003c\/p\u003e\u003cp\u003eIt can also be used on Perko 0542 and 0543 fills when the plastic cap retainer system is removed. This makes sense for owners who already have a compatible Perko vented fill in place and want keyed control at the fill opening without changing the whole assembly.\u003c\/p\u003e\u003ch6\u003eInstallation and use\u003c\/h6\u003e\u003cp\u003eThe insert presses into the throat of a compatible fill and locks against the hose bib when fully seated. On Perko 0540 through 0591 fills, the tab at the top of the insert should align with the vent opening notch so the insert does not rotate during removal.\u003c\/p\u003e\u003cp\u003eTo remove it for fueling, the key is turned counterclockwise 90 degrees, which retracts the locking cams so the insert can be pulled out by the key. On older fills, the top of the fill neck needs a smooth transition inside the opening for the insert to seat and come back out cleanly.\u003c\/p\u003e","brand":"Perko","offers":[{"title":"Default Title","offer_id":52023082549429,"sku":"QBP330069","price":52.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0977\/8171\/1029\/files\/1330356_qbp330069.webp?v=1780191684","url":"https:\/\/www.qualityboatparts.com\/products\/qbp330069","provider":"Quality Boat Parts","version":"1.0","type":"link"}
