{"product_id":"walbro-255-lph-universal-in-tank-fuel-pump","title":"Walbro 255 LPH Universal In-Tank Fuel Pump","description":"The Walbro 5CA400HP is a universal in-tank fuel pump designed to replace the low-pressure pumps found in many GM TBI vehicles. These original pumps typically provide only around 20 PSI, which is insufficient for most aftermarket EFI systems like Sniper EFI, Terminator EFI, FAST, and FiTech. This kit enables the installation of a true high-pressure EFI pump, ensuring compatibility with appropriate return-style fuel pressure regulators.\n\nThis high-performance fuel pump kit is rated to operate at 13 volts and delivers a minimum flow of 255 liters per hour at 43 psi. It is specifically designed for gasoline and is not compatible with E-85 fuel. The pump is typically located in-tank. The 5CA400HP model is capable of supporting 500+ horsepower. The source material also indicates that the standard 5CA400HP produces 267 LPH at 40 PSI and 245 LPH at 60 PSI (at 13.5 volts), with near-linear flow characteristics up to 110 PSI.\n\nFor optimal performance and engine safety, it is recommended to choose a fuel pump that flows 15-20% more fuel than your engine's peak horsepower requirement. This provides a buffer in case of voltage drops, such as during a 1\/4-mile pass. Additionally, it is strongly recommended to replace all existing rubber fuel lines when upgrading to this fuel pump, especially on vehicles that originally had low-pressure pumps.","brand":"Walbro","offers":[{"title":"Default Title","offer_id":52663408656696,"sku":"5CA400HP","price":135.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687141680.jpg?v=1784326670","url":"https:\/\/store.motormia.co\/products\/walbro-255-lph-universal-in-tank-fuel-pump","provider":"MOTORMIA","version":"1.0","type":"link"}
