Where most bucketed kits lock you into a single power level, this one is modular: you buy the stage that matches your build today and step up later with a Precision Raceworks pump upgrade module instead of replacing the whole assembly.\u003cbr\u003eAll six stages retain the factory Venturi effect inside the bucket, which is what keeps the pump fed at low tank levels and under sustained cornering loads, and every stage is available as a kit you assemble yourself or as a fully assembled drop-in unit.\u003cbr\u003eChoosing Your Stage\u003cbr\u003e\u003cbr\u003e\u003cbr\u003eStage 2 (2.6 LPM): Single Walbro 450.

Add the In-Tank Fuel Filter \u0026amp; Regulator (V2) to reach the advertised numbers.\u003cbr\u003eShould I choose Kit Only or Fully Assembled?Kit Only keeps your own bucket housing and costs less if you are comfortable following Precision Raceworks' assembly instructions. Fully Assembled is built to order and ships ready to drop in, which suits owners who plan to have a shop install it.\u003cbr\u003eCan I drive on a low tank with the higher stages?Stage 3 and up add pump capacity outside the factory Venturi. Precision Raceworks recommends keeping at least a quarter tank and avoiding sustained road course driving on these stages.\u003cbr\u003eHow do I know which stage fits my power goals?Pick the stage rated above your target whp with some margin, since real-world fuel demand varies with boost, tune, and ambient conditions.
