{"product_id":"fuel-surge-tank-2","title":"Fuel Surge Tank","description":"It maintains a buffer volume of fuel, ensuring the primary pumps never encounter air. The OEM in-tank pump functions as a lift pump, continuously replenishing the surge tank, while excess fuel is routed back to the main tank.\n\nThis surge tank supports running one, two, or three fuel pumps (the E5LM version supports one or two) with a merged single outlet for simplified external plumbing. Pump staging is also supported for setups using check-valve equipped pumps. The 2024 redesign incorporates a tangential swirl pot for enhanced air and foam separation, improved brushless pump support, anti-rotation high-current electrical studs, and an anodized aluminum pump mounting bracket. All internal wiring is compliant with gasoline, ethanol, and methanol, making it suitable for various fuel types.\n\nConnectivity includes a 10AN ORB pump outlet port (with an 8AN male adapter pre-installed) and 8AN ORB overflow, supply, and return ports (each with a 6AN male adapter pre-installed). These fittings are swappable for different setup requirements and are sold separately. Filtration options include a standard press-in filter sock for the brushless E5LM version and a stainless steel mesh inlet screen for other pump versions, serving as pre-pump filtration. The three filtration chambers are isolated to prevent fuel cross-contamination. If fewer than three pumps are used, the empty port on the inlet screen does not require blocking.\n\nProper installation is critical: the stock tank pump outlet must connect to the MPFST supply port, the stock tank return inlet to the MPFST overflow port, the MPFST pump outlet to the engine and fuel rail, and the MPFST return port to the fuel pressure regulator's return. For returnless vehicles, a return port must be created on the stock tank for the overflow; blocking this port is not permissible. All necessary hardware for pump installation (excluding the pumps themselves) and power connections are included.","brand":"Radium Engineering","offers":[{"title":"Default Title","offer_id":52689351967032,"sku":"7105550123183","price":549.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687134470.webp?v=1784905557","url":"https:\/\/store.motormia.co\/products\/fuel-surge-tank-2","provider":"MOTORMIA","version":"1.0","type":"link"}
