The dual check-valve design primes quickly and resists fuel draining back to the tank — a common complaint with single-valve or low-quality aftermarket bulbs.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCommon Issue:\u003c\/strong\u003e The most frequent ordering mistake is selecting a primer bulb by appearance rather than hose diameter. Scepter's 1\/4 in., 5\/16 in., and 3\/8 in. bulbs look nearly identical on the shelf. Measure the inside diameter of your existing fuel hose before ordering. If your current bulb fits but drains back between uses, the check valves are likely failed — this is a normal wear item and does not indicate a fuel-system problem beyond the bulb itself.\u003c\/p\u003e","brand":"WEST","offers":[{"title":"Default Title","offer_id":43564075188260,"sku":"07494","price":17.18,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/0a81a336-e9bf-4bb2-8e14-bda7ad6eae1b.png?v=1784053481","url":"https:\/\/marisolmarine.com\/products\/scepter-marine-primer-bulb-07494","provider":"Marisol Marine Company","version":"1.0","type":"link"}
