{"product_id":"remanufactured-fuel-injection-pump","title":"Remanufactured Fuel Injection Pump","description":"The Bosch VP44027P is a remanufactured fuel injection pump, specifically a Standard Output (SO) model designed to deliver 235 horsepower. It fits 1998.5 through 2002 Dodge Cummins Turbo Diesel trucks equipped with either an automatic or a 5-speed manual transmission. This pump is a common replacement for the factory-installed unit, often referred to as the most common pump found on Dodge Pickup Trucks.\n\nThis unit is rebuilt by a certified Bosch shop and includes all necessary Bosch upgrades and updates, featuring new electronics and a steel housing for enhanced durability. The VP44 is a highly advanced pump that utilizes the vehicle's computer (PSG) for precise control of both fueling and timing. However, it is sensitive to lift pump performance; a failing or insufficient lift pump (below 5 psi, with 13 psi recommended) can lead to overheating and pump failure.\n\nInstallation requires careful attention to keyway alignment to prevent timing errors and P0216 codes. It is strongly recommended to replace the feed pump simultaneously with the injection pump, as the VP44 relies on fuel flow for cooling and lubrication. Performance chips can increase operating temperatures, potentially leading to rotor seizure and pump failure, especially when throttle is reduced. Alternatives like larger injectors or ECM-direct chips can increase horsepower without excessively heating the fuel pump. Troubleshooting common VP44 codes such as P1688 or P0216 may indicate a defective injection pump, though checking lift pump pressure first is advised. These codes and fitment notes relate specifically to Dodge pickups and are not applicable to other ISB engine applications.","brand":"Bosch","offers":[{"title":"Default Title","offer_id":52687256420664,"sku":"VP44027P","price":1334.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/662156084.webp?v=1784881911","url":"https:\/\/store.motormia.co\/products\/remanufactured-fuel-injection-pump","provider":"MOTORMIA","version":"1.0","type":"link"}
