This Nostrum kit upgrades the direct injection side, replacing the camshaft-driven high pressure fuel pump with a Big Bore unit that flows 47% more fuel than the factory pump at 1.86 cc\/rev and 240 bar. That is the side that limits a boosted or ethanol-fuelled Coyote first, which is why this is the part people reach for before touching injectors. It is welded stainless with a CFD-optimised damper housing and integrated SAE quick-connect fittings, it retains the standard low pressure fuel line, and Nostrum designed the kit to be fully reversible to the factory fuel system with no modification of OEM parts and no trimming of the intake.\u003c\/p\u003e\u003ch2\u003eBest For\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e2018 on Mustang GT and 2021 on Mach 1 owners adding a supercharger, turbo or nitrous\u003c\/li\u003e\n\u003cli\u003eCoyote builds moving to pump E85, which needs far more fuel volume than petrol\u003c\/li\u003e\n\u003cli\u003eOwners who want a fuel upgrade that can be returned to standard without cutting parts\u003c\/li\u003e\n\u003cli\u003eCars where direct injection is the limit and the port injectors still have headroom\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWhich Side Of The Fuel System This Fixes\u003c\/h2\u003e\u003cp\u003eOn a Gen 3 Coyote the ECU blends direct and port injection by load and conditions. Direct injection does the heavy lifting where cylinder pressure is highest, so when a power adder or a high ethanol blend arrives, the high pressure pump runs out first. Adding 47% more pump capacity raises that ceiling without touching either injector set. On an earlier 2011-2017 5.0 the picture is different: those engines are port injected, and the route there is the \u003ca href=\"\/products\/nostrum-950cc-ford-mustang-5-0l-coyote-pfi-injector-set\"\u003e950cc port fuel injector set\u003c\/a\u003e.\u003c\/p\u003e\u003ch2\u003eKey Specs\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eManufacturer: Nostrum High Performance\u003c\/li\u003e\n\u003cli\u003eProduct Type: direct injection high pressure fuel pump kit\u003c\/li\u003e\n\u003cli\u003eSKU: H086-1438\u003c\/li\u003e\n\u003cli\u003eVehicle Application: 2018 on Ford Mustang GT and 2021 on Mustang Mach 1, Gen 3 Coyote 5.0\u003c\/li\u003e\n\u003cli\u003eFlow: 47% more than the factory pump\u003c\/li\u003e\n\u003cli\u003eGeometric displacement: 1.86 cc\/rev\u003c\/li\u003e\n\u003cli\u003eMax operating pressure: 240 bar\u003c\/li\u003e\n\u003cli\u003eDesign: welded stainless, CFD-optimised damper housing with integrated SAE quick-connect fittings\u003c\/li\u003e\n\u003cli\u003eRetains the OEM low pressure fuel line; returns to standard with no OEM parts modified and no intake trimming\u003c\/li\u003e\n\u003cli\u003eIncluded Items: Big Bore HPFP, vacuum-brazed stainless tube assemblies, anti-vibration P-clamps, locating bracket and mounting hardware, flange with O-ring and installation tool, harness connector, installation guide, data card, certificate of authenticity\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eFitment And Setup Checks\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eFits the Gen 3 Coyote 5.0 in the 2018 on Mustang GT and the 2021 on Mach 1.
