Hi all, have a 1984 w123 230E. Owned for nearly last 40 years.

We have a problem with the fuel pump maybe someone can help us on?

The fuel pump doesn't seem to be working, despite being replaced several times as part of fault finding in last few weeks (replaced with German made unit MotorService brand).

We've drained the fuel tank and checked the relay providing power.

We are wondering if the accumulator might be the culprit? Or something else? Many thanks!
