I agree, it is certainly cleaner than mine though mine isn't too bad.

Okay. Charlestown, NH is 115' in elevation. Ran two tests. 1st one was with the switch by-passed and it was 13.86 seconds. Problem with that run though. Noticed acceleration was good and then dropped off at about 45 MPH. A vacuum hose had popped out from my by-pass. Put everything back the way they are supposed to be and ran 0-60 in 12.71 seconds. I will run a couple more tomorrow so that I can get an average (besides it is fun). Let me know what you think.

I know I have some existing vacuum leaks to contend with. Since I have installed the new vac pump, I am going to start replacing vacuum lines and connectors.

Steve,

12.7 seconds in a station wagon is pretty darn good. I'd consider tweaking the ALDA, especially if the car doesn't leap off the line, and/or you feel a "kick" around 2000-2500rpm as the turbo spools up. With the ALDA adjusted correctly, there should be smooth power off idle pretty much to redline (or the ~4800rpm shift points). That may help pick up another half second or more.

Regardless, I think your car is OK on power...!

gsxr,
Okay. Today's run resulted in 11.9 seconds. Changes since yesterday include removed everything as shown in your photo, replaced numerous vacuum line rubber connections (several quite likely leaked), improved the connection of the single line that goes into the "vacuum control valve" shown as #65 on the schematic and what I have been calling the modulator, freed the micro type switch under the throttle pedal so it "clicks." Before doing all of the above the shifting flared between 2 & 3 and it no longer does.

I am quite pleased with the changes and need to tackle other projects.

If I put a boost gauge (small LED one offered by Speedshop.org) where would I plumb it into?

Sounds great! They're sure nice cars once you get them running as Mercedes intended them to, huh?

If you were to add a boost gauge, I would plumb it with a "T" close to the ALDA, or at least into the line the feeds the ALDA.

1) Nope, sorry, you'll need to inventory under your hood.
2) It depends on the location. Most of the time, yes, you really need the angled fittings.
3) Larger diameters are on the vent tubes and, IIRC, for the vac reservoir.
4) Clamped tubes are for pressure, not vacuum. The hose isn't special, generic is fine.
5) The one "shaped" hose on the VCV should be available via the dealer if required.
6) Silicone might be ok if the size is correct, but I'm not sure if it's worth the hassle / expense.

The filter (aka "strainer") is shown in the EPC, engine group 14, subgroup 135. Part number is: 000-078-04-56

Current MSRP is $8.50.

I have a 1993 Mercedes 300D 2.5 Turbo OM602. I am not looking to increase power or eliminate any hoses/lines. I would just like to replace all of mine because they all appear to be original and in bad condition. I am sure some are leaking because my fuel shutoff does not work every time I turn the key to off.

The problem I am having is that some Black Rubber hoses appear to be larger than others, for instance, the hose on the EGR appear to be larger.

Can someone help me out with identifyin the diameter of inside diamater of the hose/lines.

Can anyone tell me if these are the same specs for w123/om61x ?
