{"product_id":"fuel-it-fuel-pump-upgrade-kit-n54-n55","title":"Fuel-It! Fuel Pump Upgrade Kit N54\/N55","description":"The Fuel-It! FI-650HP fuel pump upgrade kit is engineered for BMW E-Chassis vehicles equipped with N54 and N55 engines, targeting power goals of up to 650 wheel horsepower. This system aims to provide a cost-conscious fueling solution by enhancing stock components for everyday driving while incorporating a secondary pump that activates under high boost conditions. This approach ensures reliability and drivability without the need for extensive modifications to the stock bucket, wiring, or plumbing, making it a reversible upgrade.\n\nThe kit utilizes the stock pump assembly for regular use and adds a secondary pump, such as a Walbro 450 or optional Walbro 525, that runs in parallel. Installation involves adding the secondary pump assembly alongside the stock unit in the fuel tank and connecting an additional wiring harness. Options are available to include a new stock LPFP, a new tophat, or a complete new stock LPFP assembly for those whose stock pump may be worn or who prefer a simpler installation.\n\nProper operation of the secondary pump requires it to run only under high boost conditions, not full-time. This is typically managed via a Hobb's switch (available in 4 PSI or 15 PSI options) or by utilizing an existing port injection controller. Running the secondary pump continuously can lead to increased fuel temperatures and potential component failure. The kit includes a Walbro pump, custom fittings, pump brackets, necessary hardware, fuel line, a replacement PITA clip, and optional wiring harness and tophat.\n\nThis fuel pump upgrade is compatible with the following BMW E-Chassis models within specific build date ranges: 1' E88 (11\/2006 — 10\/2013), 1' E82 (11\/2006 — 10\/2013), 3' E90 (02\/2004 — 09\/2008), 3' E90 LCI (07\/2007 — 12\/2011), 3' E91 (02\/2004 — 08\/2008), 3' E91 LCI (07\/2007 — 05\/2012), 3' E92 (05\/2005 — 02\/2010), 3' E92 LCI (11\/2008 — 06\/2013), 3' E93 (09\/2005 — 02\/2010), 3' E93 LCI (11\/2008 — 10\/2013), and X1 E84 (04\/2009 — 06\/2015). Note: While compatible with the S65 engine in E9X M3 models, specific tophat and bucket assembly options are not available for them.","brand":"Fuel-It!","offers":[{"title":"Default Title","offer_id":52688435282232,"sku":"FI-650HP","price":399.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/663175676.webp?v=1784890089","url":"https:\/\/store.motormia.co\/products\/fuel-it-fuel-pump-upgrade-kit-n54-n55","provider":"MOTORMIA","version":"1.0","type":"link"}
