Fuel pump specialist outlines key considerations for selecting single and dual in-tank fuel pump configurations.
Hong Kong, October 20, 2026 -- OSIAS is highlighting the differences between 255LPH and 340LPH in-tank fuel pumps to help vehicle owners, workshops and automotive enthusiasts make informed choices for replacement and performance applications.
Owned by OUTONG AUTO SPARE PARTS INC, which was established in 2006, OSIAS operates as an industrial and trading company focused on producing and selling fuel pumps. According to the company, its experience includes more than 10 years of fuel pump production and custom single and dual configurations using 255LPH and 340LPH in-tank pumps.

Understanding the Flow-Rate Difference
LPH stands for litres per hour and describes a pump’s fuel flow under specified test conditions. The numerical difference between 255LPH and 340LPH is 85 litres per hour, meaning the higher figure represents approximately 33% more nominal flow when measured under equivalent conditions.
However, these figures should not be treated as a guarantee of fuel delivery in every vehicle. Operating pressure and voltage at the pump affect available flow. Buyers should compare model-specific performance data at their intended operating pressure rather than relying on the headline rating alone.
Choosing a 255LPH In-Tank Fuel Pump
A 255LPH pump may be suitable for an application where its verified output meets the engine’s fuel requirements with an appropriate reserve. Selection should account for the engine specification, intended power level, fuel type and operating pressure.
For a replacement installation, physical fit is equally important. Pump dimensions, inlet and outlet positions, electrical connections and compatibility with the existing hanger assembly should be checked before purchase.
When a 340LPH Pump May Be Appropriate
A 340LPH pump may offer additional flow capacity for applications with greater fuel demand, provided its performance at the required pressure supports the intended build.
A higher flow rating does not automatically increase engine power or improve fuel economy. The pump must work within a correctly specified fuel system, including suitable injectors, regulation and electrical supply. Fuel compatibility also depends on the particular model; buyers should confirm any ethanol or E85 suitability from its specifications.
Single and Dual Pump Configurations
OSIAS’s custom single and dual configurations provide options for different installation requirements. A single-pump arrangement may meet an application’s needs, while a properly engineered dual-pump system can provide additional fuel delivery capacity.
The output of a dual system should be evaluated as a complete installation. Wiring, pump control, plumbing and pressure regulation influence its performance, so adding two nominal ratings does not establish the fuel flow that will reach the engine.
OSIAS’s Fuel Pump Focus
The OSIAS catalogue includes high-pressure fuel pumps, in-tank and external high-flow pumps, fuel pump assemblies and related fuel system components. Its website also provides a vehicle selection feature and dealer and distributor programme information.
Customers can explore the range through OSIAS BRAND and review individual product specifications before selecting a pump for their vehicle or custom project.

A country need not run out of money to find itself in a debt crisis. It only has to run short of US dollars to pay for its energy.

According to the World Bank’s...
