Since 2006, OSIAS had started to manufacture the fuel pump for aftermarket. These fuel pumps are all made up of first-class material in order to strengthen the durability and extend the usage life. 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.

The 340 Fuel Pump is a high-output, in-tank, electric fuel pump that fits most popular EFI applications. It is a compact, lightweight pump that bolts into many existing hanger assemblies. What sets the 340 Pump apart is its superior flow throughout a wide pressure range. Compared to other popular aftermarket pumps, at 40 psi the 340 boasts more than 340 lph. That's over 30% more 255lph pump. This pump is ideal for applications requiring more flow while retaining the factory lines and mounting provisions available in the OE configuration. The 340 is also perfect for use as a universal replacement for applications that require more flow to support forced air power adders such as turbo and supercharged applications.
