Parts for your 2007 Daihatsu Bego-Fuel pump

2007 Daihatsu Bego fuel pump — what it does and how to look after it

Technical sources confirm the 2007 Daihatsu Bego runs an in-tank electric fuel pump. The Daihatsu Terios/Bego J200/J210 Series Workshop Manual (Fuel System), the Toyota Rush J200E Electrical Wiring Diagram showing the circuit opening relay and pump control, and the Daihatsu Electronic Parts Catalogue listing a “fuel pump assembly (with gauge)” for J200 models all identify the pump as part of the sender module inside the tank. So yes—this model is fitted with a fuel pump, and it’s a key bit of kit for the EFI petrol engine.

On the Bego’s EFI setup (commonly the 3SZ-VE 1.5-litre), the pump’s job is to draw petrol from the tank and deliver it at stable, high pressure to the rail and injectors. The module typically includes the pump motor, an internal pressure regulator (returnless layout), a strainer (sock) and the fuel level sender. The engine ECU drives the pump via the circuit opening relay for safe, on-demand fuel delivery—quietly humming away under the rear seat area.

There’s no routine replacement interval for the pump, but a few smart habits will keep it happy. Avoid running the tank near empty (the fuel cools the pump), and use clean, quality petrol. If symptoms pop up—long cranks, flat spots on hills, loud whining from the tank, or lean fault codes—get a proper pressure test done before ordering parts. Typical working pressure is around the low-300 kPa range
