The FHST system independently supplies fuel to the port injectors, while the direct injection system remains undisturbed using the OEM fuel pump. The surge tank functionality ensures that a fuel reserve is kept trapped around the aftermarket fuel pump to prevent fuel starvation.\u003c\/p\u003e  \u003cp\u003e \u003c\/p\u003e  \u003cp\u003e\u003cstrong\u003eHOW THE FHST WORKS\u003c\/strong\u003e\u003c\/p\u003e  \u003cp\u003eThe OEM system contains a fuel pump, fuel pressure regulator (FPR), fuel filter and multiple venturi jet pumps (not shown in diagram above). In factory form, the OEM fuel pump supplies fuel to the engine through the fuel filter which has an integrated FPR. This pressure regulated fuel is also used as the driving force for multiple venturi jet pumps. These OEM venturi jet pumps transfer fuel from opposite ends of the fuel tank to the OEM pump basket keeping it full.\u003c\/p\u003e  \u003cp\u003eThe Radium FHST drops into the LH opening of the fuel tank which is the opposing side of the OEM fuel pump on the RH side of the fuel tank. It does NOT disrupt any aspect of the OEM fuel system and still uses all OEM fuel level sensors. Fuel is still supplied to the engine using the OEM pump, OEM filter, OEM FPR, and OEM venturi jet pumps. The FHST uses a separate pump outlet and return inlet making it ideal for an independent port injection or custom fuel system.\u003c\/p\u003e  \u003cp\u003eThe FHST canister is supplied with fuel from the 3 following sources:\u003c\/p\u003e  \u003col\u003e \t\u003cli\u003eThe LH OEM venturi jet pump now fills the FHST canister first and then the overflow bleeds into OEM fuel pump basket, just like factory.\u003c\/li\u003e \t\u003cli\u003eThe returning fuel from the aftermarket FPR (included in 20-0867-03 and 20-0867-05) enters the FHST canister through a diverter (shown below) to prevent aeration and fuel foaming.\u003c\/li\u003e \t\u003cli\u003eThe three 1-way fill valves at the bottom of the surge tank flow 355LPH each (1,065LPH total).
