No. It increases pump speed capability, but ECU calibration and supporting hardware (injectors, rail, lines) are needed to realise extra fuel delivery. Which variant do I need — HP3 or HP4? Stock 1KD uses a 2-rotor HP3 pump. If you’ve converted to a 3-rotor HP4 (1VD style), select the HP4 bracket. Check your pump before purchase. Is this a direct bolt-on? Mechanical fitment is straightforward, but wiring extension and fuel pipe adjustment are commonly required. Professional installation recommended. Is this road-legal? Intended for off-road/competition use where permitted. Check local regulations.
