Td5 Fuel Pressure Regulator - Defender Td5 & Discovery 2 Td5

If your Td5 fuel pressure regulator is leaking or not maintaining correct fuel pressure, the right fix depends on which version you have and whether you need a repair, a rebuild or a full replacement regulator.

Fuel pressure regulator leaks on a Td5 are also often mistaken for rear crank seal leaks, because diesel runs down to the same area and can appear through the gap in the bellhousing directly below the regulator, picking up dirt and thickening along the way.

This page brings together our Td5 fuel pressure regulator parts for Defender Td5 and Discovery 2 Td5, including genuine regulators, OEM regulators, the Bosch rebuild kit and the repair hose / pipe option for late-type setups.

• Early 1 pipe regulators for 10P / 11P applications
• Late 2 pipe regulators for 15P / 16P applications
• Full regulator replacements in genuine and OEM options
• Lower-cost repair options where a full regulator is not needed
• All fit Defender Td5 and Discovery 2 Td5 (all Td5 engines)

If you already know which version you need, you can go straight to the correct product. If not, the most important thing is to check whether your engine uses the early 1 pipe setup or the later 2 pipe setup before ordering.
