Fuel Injection Supply Pump for Toyota SUVs

This OE-grade fuel injection supply pump keeps your Toyota’s engine fed with the right fuel pressure and flow. Built for tough duty, it delivers stable starts, smooth idle, strong mid‑range pull, and clean emissions. Perfect for restoring factory performance on heavy-duty 4x4 use.

Why this part is needed ⛽

Engines need precise fuel at every rpm and load. The pump draws fuel from the tank, removes air, and pressurizes it for the rail/injectors. Correct pressure means better torque, economy, and reliability on-road and off-road.

How it works ⚙️

Driven by the timing system or internal motor, a metering valve and plungers build high pressure. The ECU modulates the control valve to match demand, while an internal regulator keeps rail pressure steady for crisp throttle response and clean combustion.

What happens if it breaks ⚠️

Common symptoms: long crank, stalling on climbs, flat acceleration, black/white smoke, poor MPG, rail pressure DTCs, or metal debris in the filter. Continued use can damage injectors, overheat pistons, and lead to a hard no‑start.

Tech tips for install ✅

Replace fuel filter, seals, and gaskets; flush lines; prime and bleed carefully; verify return flow; torque to spec; and perform pressure/learn procedures with a scan tool. Use clean, quality fuel to protect the new unit.

Fit and quality

Direct-fit ports and brackets, calibrated pressure curve, low noise, and durability for low‑sulfur fuel. Ideal for Land Cruiser injection pump replacement and Toyota 4x4 supply pump service.
