When power is removed, a return spring releases the lever for the next start.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eQ:\u003c\/strong\u003e What might cause a shutoff solenoid to fail? \u003cstrong\u003eA:\u003c\/strong\u003e Common issues include a burned-out coil from continuous voltage, internal corrosion from moisture, or a stuck plunger due to debris. Replacing with this solenoid restores the shutdown function without needing to replace the entire fuel pump assembly.\u003c\/p\u003e\u003cp\u003e\u003cem\u003eSlight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.\u003c\/em\u003e\u003c\/p\u003e","brand":"Part Outfitters","offers":[{"title":"Default Title","offer_id":46610062016698,"sku":"ZZ3F09855","price":116.39,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0779\/2476\/1786\/files\/s-l1600_c41ca4aa-e0fa-498d-8e57-bbfe1f897dec.jpg?v=1788998564","url":"https:\/\/partoutfitters.com\/products\/12v-shutoff-solenoid-for-cat-3204-3304-3304b-3306-3306b-3406b-3406c-ht400-3306c","provider":"Part Outfitters","version":"1.0","type":"link"}
