My first thought was most of the crud would just float about the tank, end up on the bottom, and then on the screen again. My second thought was along vwnate's thinking.

My third thought was the first stage filter would really take it in the teeth, but then the crud wouldn't be in the tank...

Worst case, I start loosing power somewhere with a plugged filter, but I have 5 spare in the trunk... I just might try that.

I've had so many come into the shop after a mistake like this , have at it , don't cry later .

Nah, it's the internet. I'm free to ignore informed advice then b!tch up a storm after the fact...

Still... it seems just slick enough to feel like a good free-lunch idea, without being 'kerosene in the oil' crazy... you know?

vwnate1 · #34 10-06-2015, 05:06 PM

I do know !

.

I have learned much by working on old junkers and occasionally breaking my own toys.....

.

It's just a pisser to get crud into the fuel injection system as it always seems to screw up at least one previously good injector...

As a side note, is the attached the correct blurry pixelated reference for my 240D's 616.912 throttle linkage? Would be nice to change flooring-it-on-the-freeway into passing-on-the-freeway.

Ok... so that didn't work. Once more with attachment.

vwnate1 · #36 10-06-2015, 05:14 PM

?? I see no attachment......

Taking the time to set up the rod lengths really was nice ~ I too pass on the freeway a lot and I don't actually drive my 240D fast , that's the 617's job

.

I'm still looking for '82 240D linkage parts and switchover valve cover .

Link attached to my last post. Found it here under the Engine Manual section 30-300...

That link should be next to the forum header...

My line reversal advice is the first thing told to people who need to diagnose a clogged tank strainer. It's not the worst thing you can do, it's diagnostics. If anyone thinks that's a final fix they're wrong. If it works it means you have to remove the tank and clean it.

Also, if the crud is big enough to get stuck on the tank strainer, you'd be out of your mind to think it can go through the 10 micron secondary filter and into an injector... That just isn't going to happen.

What I've done in the past is blow out the strainer like described, and dose the tank with Clear Diesel by Power service. VStech had excellent luck with it in his 190D as well.

Oh make no mistake, I'm going to do it. Might get another main filter on order first... I've seen big crud turn to lot's and lot's of fine particulate crud in one of our flow calibration systems.

Removing the fuel tank in one of these cars, is sooooooo simple to do! I recommend at minimum every 30 years this should be done....Gives one person a chance to replace the screen, hoses and clean the sender...

I still stand by my remove the ADA for extra horsepower....

Removing an ADA from a NA 300D

leathermang · #41 10-06-2015, 06:52 PM

OK.... I removed my 240d 123 fuel tank and took it in the pickup truck to the local car wash.... and blasted out the inside...
However, I would not do it that way again.... it was easy to take out and put back in..
but I figured out that the position of the ' access' holes are spaced around the tank in a manner which makes it feasible to blast it clean with it IN the car...
Of course if you do not have a power washer at home... fine to take it out and do like I did at the car wash....

vince77 · #42 10-06-2015, 10:16 PM

I just filled the tank yesterday... so yea, excuses excuses. Actually, I just have no desire to pull any fuel tank, but I'm sure I'll have to someday.

My ADA isn't hooked up to anything at the moment, and I didn't think it odd since I've seen so many pictures with that tube vented. It's probably not doing anything now but I might pull it once I get my throttle linkages in order.

The ALDA on turbo cars needs to be hooked up to the intake. The ADA on naturally aspirated cars only adjusts the pump fueling by a small amount to compensate for atmospheric pressure changes at different altitudes. That would prevent a car that was tuned for the Cali coast from smoking when you take it to Denver, Colorado. The small nipple is supposed to be open to the air because that is its input. It is purely to prevent any extra fuel from being injected that the atmospheric Oxygen content cannot burn. No O2 to burn it, no need to for it to even be there (it makes smoke and raises EGTs so it's bad). The higher you go, the less dense the air is and the less O2 there is.

Hmm... well I've added it to the list. Don't see a reason to mess with it yet, I've plenty of other projects. But someday...

The video says 240D. But the lighted sunvisor mirror says 300D (unless those options are a-la-carte for W123s in Europe).
Wasn't impressed with the big screws holding the wood trim to the dash.

My solid-body 240D, with a factory replacement engine, is pretty quiet when revved or cruising on the highway and passing power is decent. When pushed, that engine sounds closer to a 4-cyl gasser. It's actually quieter than my '84 Euro 300TD. Then again, the Euro has more rust and perhaps less soundproofing and maybe the open cargo bay magnifies noise.
Either car is serene compared to my first diesel - a $200, rusty & tired automatic 240D, well thrashed by the PO's teenagers. That car was nearly deafening at speeds above 60 mph!

Happy Motoring, Mark
