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.
