The all procedures are executed strictly according ISO/TS1649 and QS900 standard which is highest quality class for OEM in auto industry.Every pump is 100% tested before shipment. Brand story: Since 2006, OSIAS has been producing fuel pumps for the aftermarket. These fuel pumps are made of first-class materials to enhance durability and extend service life. The brand “OSIAS” is evolved from “oasis", we believe that desert needs "oasis" to supply water just like cars need the pump to supply fuel. Started by performance enthusiasts in 2006, OSIAS set out with one goal in mind: To design reliable, affordable fuel pumps with this concept“less fuel, more power". Workshop of the factory: 1.【340lph fuel pump】Designed for high output naturally aspirated and forced induction EFI vehicles and tested to flow 340 lph at 43 PSI,E85 compatible; In-Tank design; high flow fuel pump 2.【PERFORMANCE】OSIAS performance fuel pump choose composite Turbine Impeller design bringing quiet operation 3.【DESIGNE】39 millimeter diameter fits most applications; Offset inlet design eases installation and each pump individually tested ,Made of High Quality & Durable Material That Meets OE Standard; Use carbon commutator and carbon brush 4.【Technical Data】Power rating given at 43 PSI, 13.5 Volt at the pump with a BSFC of .5, flow capability for horsepower support is ultimately dependent on fuel hose diameter and system electrical voltage and amperage capabilities 5.【Quality & Warranty】LIFETIME WARRANTY,Please check your car information before purchase. Description: 1: Award-winning OE technology 2: Designed for engines with more than 750 HP 3: Outperforms all current market in-tank fuel pumps 4: Dual channel turbine design for maximum 5: efficiency under high-pressure and high-temperature applications Include: Fuel Strainer: 30 micro gradient density material.Universal connector.Sponge SleeveRubber hoseStainless Steel Clamps: 2pcs. Specifications: 255LPH (43PSI), 190LPH (80PSI), Operating Pressure: 15-90 PSI, final fuel pressure set by regulator. Applicable fuel: gasoline, E85 and ethanol gasoline with less ethanol content than E85. (high impurity gasoline will directly affect the pump life) The diameter of 255LpH high-flow INTANK electric fuel pump may be different from the original model, but it will not affect the use.Hoses, filters or other equipment may need to be replaced.Professional installation is highly recommended.
