This is an OEM fuel regulator block for the Land Rover Defender and Discovery 2 TD5. These are notoriously prone to leaking and generally come with the fuel pipes attached although these pipes never fail. You can just use your existing ones with this item.
⚠️ CRITICAL TECH TIP: Avoid Immediate Leaks!
When replacing your Td5 fuel pressure regulator, always fit a new ERR6761 gauze filter O-ring.
When replacing your Td5 fuel pressure regulator, always fit a new ERR6761 gauze filter O-ring.
The original rubber O-ring sits deep inside the cylinder head cavity. Over time, engine heat causes it to harden, flatten, and lose its seal. Reusing this old, compressed O-ring is the #1 cause of brand-new regulators leaking immediately after installation.
