{"product_id":"ultra-double-pumper-4-barrel-750-cfm-carburetor","title":"Ultra Double Pumper 4-Barrel 750 CFM Carburetor","description":"The Holley Ultra Double Pumper Model 4150 carburetor delivers 750 CFM of airflow with a four-barrel, square bore design. Constructed from aluminum, it offers a significant 43% weight reduction compared to other materials, contributing to both performance and durability. This model features mechanical secondaries for enhanced performance and a factory-preset electric choke for easy startups.\n\nIt includes advanced features such as 4-corner idle for precise idle control and stability, and four vacuum ports. A built-in clear fuel level sight glass allows for easy adjustments without mess. The polished black billet aluminum metering block and base plate provide a modern aesthetic.\n\nThe Ultra Double Pumper is designed to replace Holley, Edelbrock, Carter AFB, and Autolite style carburetors with a 5 3\/16\" x 5 5\/8\" bolt pattern. An adapter is required if your intake manifold is a spreadbore style. It is compatible with GM, Chrysler, and Ford automatic transmission kickdown linkages, though some applications may require additional parts. Holley technicians wet-flow test each unit to ensure it is ready to run upon arrival.\n\nThis carburetor is specifically intended for lightweight vehicles equipped with manual transmissions or automatic transmissions that have a high stall converter and low gearing.","brand":"Holley","offers":[{"title":"Default Title","offer_id":52688678453560,"sku":"HLY0-76750BK","price":828.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/663692762.webp?v=1784892720","url":"https:\/\/store.motormia.co\/products\/ultra-double-pumper-4-barrel-750-cfm-carburetor","provider":"MOTORMIA","version":"1.0","type":"link"}
