0000747284 Diesel fuel return valve/banjo bolt
Fuel injection pump starvation with good a good lift pump is becoming more common as the bypass valve spring gets weaker with age.
A weak bypass spring allows too much lift pump pressure to flow back to the fuel tank = starving the injection pump for proper fuel volume. The solution is to install a new (or good used) bypass valve. MB# 0000747284 Diesel fuel return valve/banjo bolt, back of injection pump by engine block, at nylon return line going to fuel filter housing.
