This allows the system to maintain stable fuel pressure even under high horsepower conditions.\u003c\/p\u003e\n\u003cp\u003eDuring extensive testing it was found that the factory low pressure fuel pump begins to experience pressure drop around 750 WHP. This issue becomes more severe when running higher ethanol blends. Tuners often compensate by increasing injector open time, but this creates inconsistent fueling and makes true flex fuel operation difficult.\u003c\/p\u003e\n\u003cp\u003eThis upgrade provides the additional fuel volume required to maintain proper fuel pressure and support higher power levels.\u003c\/p\u003e\n\u003cp\u003eWhat’s included:\u003c\/p\u003e\n\u003cp\u003eWalbro 525 fuel pump  \u003cbr\u003eVisconti fuel pump bracket  \u003cbr\u003eVisconti fuel pump 3\/8 quick connect fitting  \u003cbr\u003eVisconti replacement in-tank fuel line  \u003cbr\u003eVisconti sealed wire pass-through  \u003cbr\u003eHolley fuel mat  \u003cbr\u003eNJ style zip tie\u003c\/p\u003e\n\u003cp\u003eAdvantages over other solutions:\u003c\/p\u003e\n\u003cp\u003eKeeps the second fuel pump inside the fuel tank  \u003cbr\u003eDoes not require additional fuel lines in the engine bay  \u003cbr\u003eMaintains proper fuel pickup even at low fuel levels\u003c\/p\u003e\n\u003cp\u003eWiring:\u003c\/p\u003e\n\u003cp\u003eIf you are not running our ReFlex Sequential Port Injection Kit, you will need to activate the fuel pump relay using our non-ReFlex harness and a Hobbs switch.\u003c\/p\u003e\n\u003cp\u003e(Hobbs switch not included)\u003c\/p\u003e","brand":"Visconti Tuning","offers":[{"title":"STG1 FUEL SYSTEM UPGRADE \/ REFLEX WIRING KIT","offer_id":53007215460668,"sku":"sku-42795496702172","price":1814.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0714\/3070\/1372\/files\/visconti-m340-stage1-fuel-hat-upgrade.jpg?v=1776968476","url":"https:\/\/trucranemotorsports.com\/en-ca\/products\/g20-g42-m240-m340-stg1-fuel-system-upgrade","provider":"TruCrane Motorsports","version":"1.0","type":"link"}
