{"product_id":"fuel-hanger-surge-tank-can-am-maverick","title":"Fuel Hanger Surge Tank, Can-Am Maverick","description":"\u003cp\u003eThe Radium Engineering FHST (fuel hanger surge tank) is the ultimate solution for fuel starvation issues in the Can-am Maverick chassis. Due to insufficient baffling, fuel starvation is common when the UTV is driven aggressively. This results in unstable fuel pressure and possible engine damage from running too lean. This FHST is a fully functional fuel surge tank INSIDE the factory tank.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch4\u003eHOW THE FUEL HANGER SURGE TANK WORKS\u003c\/h4\u003e\n\u003cp\u003eThe FHST contains a fuel pressure regulator, 2 pumps, and pre and post filters. \u003c\/p\u003e\n\u003cp\u003eEven though both pumps are mounted inside the surge tank, the inlet of the lift pump is outside and transfers fuel from the open fuel tank into the FHST. Inside the surge tank, the lift pump outlet uses a reverse diffuser to control the stream, prevent overspray, and fuel foaming.\u003c\/p\u003e\n\u003cp\u003eThe surge tank pump is used to supply fuel to the engine through an integrated FPR (fuel pressure regulator). The surge tank pump is supplied with fuel from 3 different sources: the adjacent lift pump, the integrated FPR return, and three 355LPH one-way fill valves on the bottom of the surge tank that allows fuel in, but not out.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch4\u003ePUMPS\u003c\/h4\u003e\n\u003cp\u003eThe FHST requires 2 fuel pumps (lift pump and surge tank pump).\u003c\/p\u003e\n\u003cp\u003eFor the lift pump, the factory Can-Am (155LPH) pump will suffice. However, an aftermarket 38-39mm pump (such as a Walbro GSS342) can be used for extra flow into the surge tank.\u003c\/p\u003e\n\u003cp\u003eThe surge tank pump can be brushed or brushless (see pump compatibility).\u003c\/p\u003e\n\u003chr\u003e\n\u003ch4\u003eINTEGRATED FUEL PRESSURE REGULATOR\u003c\/h4\u003e\n\u003cp\u003eUsing the provided vacuum port fittings (described below), the FPR can be configured 2 different ways. If an intake manifold vacuum hose is connected to the port, the regulator will operate at a 1:1 ratio permitting fuel pressure to proportionally increase with manifold (boost) pressure. Conversely, the vacuum port can plugged and fuel pressure will remain constant (like factory).\u003c\/p\u003e\n\u003cp\u003eFurthermore, the regulator vacuum port features a 360 degree swiveling feature that is double O-ring sealed. It permits the installer to quickly point the vacuum fitting in any direction with no tools required.\u003c\/p\u003e\n\u003cp\u003eThe returning low pressure fuel from the FPR is sent back into the surge tank keeping it full.\u003c\/p\u003e\n\u003cp\u003eFuel pressure changes are made easy with a patented tool-free adjustment knob.\u003c\/p\u003e\n\u003cp\u003eThere are 4 interchangeable #10-32 threaded vacuum port fittings provided to cover all scenarios:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBarbed Fitting:\u003c\/strong\u003e A black zinc-plated 3\/16\" (5mm) barb machine from high strength steel that is compatible with the following vacuum hoses: 5\/32\" (4mm), 3\/16\" (5mm), and 7\/32\" (6mm).\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e3AN Male Fitting:\u003c\/strong\u003e A black zinc-plated adapter machined from high strength steel that is compatible with 3AN hose ends\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePush-To-Connect:\u003c\/strong\u003e A nickel-plated brass fitting with Buna-N O-rings that is compatible with hard plastic 1\/4\" OD tubing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVacuum Plug:\u003c\/strong\u003e A black oxide stainless steel screw that is used to maintain a constant (non dynamic) fuel pressure. Beginning in the mid 1990s, vehicle manufacturers started transitioning to returnless fuel systems to lower EVAP emissions. To keep temperatures lower, these regulators are mounted inside the tank and do NOT have the ability to be vacuum referenced.

We understand some users want to run an engine bay mounted regulator with a return line back to the tank. This kit makes that possible. The parts in the kit disable the built-in regulator allowing the use of an external regulator elsewhere in the system. The fuel hat features a plugged return port that can be used for the return line from the external regulator. \u003c\/p\u003e\n\u003cp\u003eFor connecting a return hose to the return port, a 6AN ORB (9\/16\"-18) fitting is required. \u003c\/p\u003e\n\u003cp\u003eA fuel pressure regulator (not included) must be installed downstream in the system.
