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 conceptless fuel, more power". Workshop of the factory: 1.340lph fuel pumpDesigned 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.PERFORMANCEOSIAS performance fuel pump choose composite Turbine Impeller design bringing quiet operation 3.DESIGNE39 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 DataPower 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
