Why TWO fuel Pressure Regulators (D-jet)?280SE W116
Why TWO fuel Pressure Regulators (D-jet)?
Found one above the inlet manifold while another under the manifold. Why do we need TWO?...and how to adjust for smooth running of the engine? Thanks in advance. NPK |

Only 1 regulator.
The other is a fuel pressure damper.
