With the ignition on, check the choke wiring for power with a voltmeter or 12 volt test light.
Or, as someone suggested, you could try wiring a pump-fuse to the ignition-coil circuit.
Otherwise, I would prefer wiring an inline fuse to the ignition-switched strip at the back of the fusebox. Your ignition switch should be able to handle the added electrical load of the fuelpump without a relay.

Happy Motoring, Mark

How would I wire a pump-fuse to the ignition-coil circuit? Which circuit is it on this car?

What amp should the fuse be? If the fuse starts blowing what would that mean?

Also, in my '66 200 gas is getting into oil. This happened I think AFTER I installed the mech pump mentioned above. Someone said that the pump could be bad (it is pumping fuel) and letting in fuel through the block?

What could the problem be?

If the mech pump is bad then I don't want to mess around with it on the 230...

Though I will try the electric first. Waiting for a couple of shops to call me about universal pumps, around 4psi-5psi

Thanks a lot guys. This provides a lot of content and future help for others.

$50 for an "old style' pump???!?!?!?!

I see them for $599 on ebay. Got a phone number or website?

I think the pressure is supposed to be around 3.5 psi. I am having a similar problem with too much fuel consumption, but I think mine is related to carbs that need rebuilt...

I've got a couple more links at home.

Also try BenzBin and... I think "Euro Parts Depot"

The reason I'm worried about the PSI is I don't want the carb flooding, or does the fuel return line solve that problem?

Use the terminal of the ballast resistor (rectangular porcelain block usually mounted on the fenderwell) on the opposite side of the ignition coil feed. Double check with a voltmeter that it is indeed getting 12 volts (key in "run" position). Wire an inline fuse holder (5 amp fuse) between this terminal and the positive feed of the fuel pump. Most pumps require you to connect the ground wire as the pumps are not "body grounded".

I run electric pumps on my three cars, no problem with flooding and in fact on one of them I actually have a "starvation" issue upon highway accelleration.

Thanks Mike.

With all this info, I'll write up a post on "hacking" a temporary fuel pump solution to people in my situation.

I'm going to practice on my 200.

Thank you!

Well, I did as you guys suggested and got the car to run. I can't believe a 40 year old 2.3l engine is this powerful in a 1805KG car. Figure should be enough for the vast majority of drivers today.

Anyone have any more info on the development of these engines and cars?
Thanks!

Hi, I'm to pick up a 1968 (w)110 230 from Seattle and bring it home to Vancouver BC.

Have you got all your paperwork in order? Some years ago a client of mine tried to bring his fathers car into Canada, many many problems. I had an engine rebuilt in BC and had all kinds of problems bring it home to Bellingham. Duty had to be paid on the most obsure items... and that was before our beloved homeland security...
feel free to drop me a line, i may be able to at least give you a place to park while you work the customs.

Hi Kurt,

THANK YOU VERY MUCH for your kind offer to park my car at your place! Though I'm going to be picking it up tomorrow =)

I have the papers in order now and the 72 hour period ended last Friday and can pick it up tomorrow (Columbus Day in US and Thanksgiving Day in Canada)

I brought in a 1992 250D from Germany through Tacoma last year and assumed that it would be as straightforward. Germans sure didn't worry about anything being exported.

You know, you took work away from American mechanics so they had to punish you =)

If you need big work done (with a licensed car to avoid problems) I know a great mechanic here (Burnaby) specializing in classic benzes on the side. He makes junk yard cars purr. His name is JR and his number is 604 720 2708

If you're ever in the area with your car let me know and drop by!

Ah yes, Homeland "Security". At its height my friend was bypassing a couple of times per week the Peace Arch crossing through the lawn to pick up his Bellingham girlfriend from the Blaine parking lot by customs. Such tight security, anything to put fear into people.
