This system installs inside the BMW fuel tank on the opposite side of the factory fuel pump and can hold one or two high-flow aftermarket fuel pumps. The OEM fuel pump is used to pump fuel into the FHST, while the pumps inside the FHST supply fuel to the engine.\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003eThe system is E85 compatible and does not require any permanent modifications for installation.\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003eRead below to see how the FHST works.\u003cspan data-mce-fragment=\"1\"\u003e\u003cstrong data-mce-fragment=\"1\"\u003e\u003cbr data-mce-fragment=\"1\"\u003e\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003e\u003cspan data-mce-fragment=\"1\"\u003e\u003cstrong data-mce-fragment=\"1\"\u003eBMW\u003c\/strong\u003e\u003c\/span\u003e\u003cspan data-mce-fragment=\"1\"\u003e\u003cstrong data-mce-fragment=\"1\"\u003e Fuel Tank\u003c\/strong\u003e\u003c\/span\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003eThe OEM saddle bag fuel tank is quite complex.

The FHST is the best solution in preventing fuel starvation. As described below, the FHST pump(s) are supplied with fuel from 3 different sources: the OEM electric \"lift\" pump, the fuel pressure regulator (FPR), and the integrated 1-way valve.\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003e\u003cbr data-mce-fragment=\"1\"\u003e\u003cimg src=\"http:\/\/www.radiumauto.com\/Assets\/ProductImages\/BMW_Tank-FHST_Plumbing_Schematic.png\" alt=\"\" data-mce-fragment=\"1\" data-mce-src=\"http:\/\/www.radiumauto.com\/Assets\/ProductImages\/BMW_Tank-FHST_Plumbing_Schematic.png\"\u003e\u003cbr data-mce-fragment=\"1\"\u003e\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003eNote that the BMW fuel pump is still retained but is now repurposed as a \"lift\" pump to fill and maintain volume in the FHST. The lift pump fills the FHST canister through a special orifice in the FHST. This keeps the required pressure for the venturi jet pump(s) to be active and deliver fuel to the lift pump. When a low demand of fuel is present, the FHST canister will overflow back into the LH side of the OEM tank. Fuel will then cycle back into the FHST through a 1-way valve integrated to the bottom of the FHST. Unlike traditional surge tanks that rely heavily on surge tank pump and lift pump flow matching, the FHST uses an extra source that negates this important relationship. No matter what is dynamically changing with the other 2 fuel sources, the high flowing 1-way valve will constantly supply fuel to the FHST canister until the LH side of the gas tank becomes extremely low. At this point, it is up to the lift pump and the FPR to supply the last few ounces of fuel to the FHST. \u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003e\u003cstrong data-mce-fragment=\"1\"\u003eIntegrated Fuel Pressure Regulator\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003eLike OEM, a fuel pressure regulator (FPR) is integrated into the unit. \u003cbr data-mce-fragment=\"1\"\u003e\u003cimg src=\"https:\/\/www.radiumauto.com\/Assets\/ProductImages\/Rotating_Assembly-2.jpg?ts=022422\" alt=\"\" width=\"600\" height=\"400\" data-mce-fragment=\"1\" data-mce-src=\"https:\/\/www.radiumauto.com\/Assets\/ProductImages\/Rotating_Assembly-2.jpg?ts=022422\"\u003e\u003cbr data-mce-fragment=\"1\"\u003eFurthermore, if an intake manifold signal is installed, this FPR can operate at a 1:1 ratio permitting fuel pressure to proportionally increase with boost pressure.
