: [MBZ] FI Pump and OOMPF '91 300D 2.5T
Howdy --
Other than slight (in my case) fuel leaking, what symptoms are the
result of DVs in need of service? I have the o-rings, springs and
copper washers to make the repairs, but after replacing the motor mounts
I'm so happy with the smoothness

The external fuel leak is the o-ring seal, doesn't affect anything
but fuel milage, and then only if it's quite large.
However, to replace the o-rings you must remove the valve holder, and
hence must replace the seals as they won't usually seal when re-
used. New springs won't hurt
Also, if your fuel tank is low and you park nose up on a slope, air will
enter the system, BTDT.

What Ok Don said is right. You should be able to replace the orings and

What Ok Don said is right. You should be able to replace the orings and
copper seals and optionally, the springs for the delivery valves to fix
the leak. There is no reason to change the inj. pump to fix the leaking
orings. Neither is likely to have relationship to oomph, or lack of.

You'd have to pull the pump and take it to them, and they probably have a
minimum charge to set it up on the

It's a Bosch pump, many shops can work on it. But
check, first. I think my local place can't/won't
do that particular pump.

Right now, the top of the FI pump below where the injector lines are
attached, are leaking. And Rusty has a good price on FI pumps. So I am
considering replacing it. I already have a few of the special timing tools
for adjusting this pump, and I am not afraid of removing

More than 6 months ago I took my ’95 E300D to the st(d)ealer to have its
lack of OOMF diagnosed. The mechanic spent most of a day ruling out things,
and he fixed a few problems along the way. He got to the point where the
cause may be in the fuel injection pump, and would need to replace it to
I don;t know about replacing the FI pump, but the leaks you describe are
what I've had on several cars. Replacing the delivery valve seals (o-rings
and a copper washer/seal) cured them. Only a few dollars - MUCH less than a
FI rebuild! I don't know that replacing the seals will affect the OOMPF
