{"product_id":"stage-2-low-pressure-fuel-pump","title":"Stage 2 Low-Pressure Fuel Pump","description":"Available in multiple stages, the Stage 2 pump features a Walbro 305, supporting up to 400 wheel horsepower on gasoline and 350 wheel horsepower on E85, with no tuning required. The Stage 3 utilizes a Walbro 450, supporting 500 WHP (450 WHP on E85) and requires tuning. The Stage 3.5 v2 uses a Walbro 535, supporting 550 WHP (475 WHP on E85) and also requires tuning. For extreme applications, the Stage 4 features dual Walbro 450 pumps, capable of supporting 1000+ WHP on E85 and requiring tuning, upgraded fuel lines, and a distribution manifold.\n\nAssembly options include a 'Kit Only' for DIY installation, where the user assembles the components into their existing fuel pump bucket, reducing downtime and costs. Alternatively, a 'New Build' option provides a fully assembled, drop-in ready unit, available for FWD or AWD vehicles. Note that for Stage 3 and higher, upgraded fuel lines are necessary, and tuning of the factory fuel pump controller is required to prevent damage; aftermarket controllers are also compatible.","brand":"Precision Raceworks","offers":[{"title":"Default Title","offer_id":52689336598840,"sku":"601-0006","price":299.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687453670.webp?v=1784905362","url":"https:\/\/store.motormia.co\/products\/stage-2-low-pressure-fuel-pump","provider":"MOTORMIA","version":"1.0","type":"link"}
