Stage 3 dual low-pressure fuel pump for the F-chassis N55\/N20 — the high-power, E85 answer on the in-tank side.\u003c\/strong\u003e Instead of replacing the stock pump, it keeps the factory primary (so the EKP behaves normally) and adds a second Walbro that runs only under boost.\u003c\/p\u003e\n\u003ch3\u003eWhat it is\u003c\/h3\u003e\n\u003cp\u003eA dual-pump kit: the stock LPFP plus a secondary Walbro 450 (525 optional) on a secondary harness, triggered under boost by a Hobbs switch — so cruise stays factory and the system only ramps when you're on it. This sidesteps the current-draw limit of a single big pump.\u003c\/p\u003e\n\u003ch3\u003eOptions\u003c\/h3\u003e\n\u003cp\u003eTwo choices in the configurator. \u003cstrong\u003eSecondary Pump:\u003c\/strong\u003e the Walbro 450 covers most Stage 3 E85 builds; step up to the higher-flow Walbro 525 for bigger power targets. \u003cstrong\u003eTrigger:\u003c\/strong\u003e a Hobbs switch is a boost-pressure switch that brings the secondary pump online at its rated boost — the 4 PSI switch brings it in early, low in the boost curve, while the 15 PSI switch brings it in higher up.
