Total waste of time sending the injection piump to Adsitco because they send it to Gus Pfister at Pacific Fuel Injection in South San Francisco.
Send the injection pump directly to Gus and he will invoice you for the repairs when it is ready. He does pumps from all over the world so Venezuela is not a problem.

I really dont know all the version, my dad owns a 250sl and there is not carburator anywhere.. only the injectors... my dad is always happy saying this old car uses that technology since those days..

It looks like you have embarked in that approach consisting of replacing parts until it works. I would suggest you find a competent mechanic able to do a precise diagnosis of the problem. These injection pumps are very reliable and I doubt it needs a rebuild at only 60.000 kms. You don't want to pay big money only to find out afterwards the problem was something else that could have been sorted out for a fraction of the expense. May be it's just the rack which is gummed up due to lack of use.

Correct response,
it may be cheaper to diagnose first,

to check the rack, pull off the ball end actuator rods, with engine idling, move both air and fuel arms by hand and observe if you can make them sync and gain rpm, then re-connect and observe.
If the rack is stuck it is easily cleaned and freed-up.

63 sl fuel pump

Hi,

I'm kind of a novice but fairly mechanical. I am rebuilding my fuel pump on my 63 230sl (the later version). Do you know where I can find the parts for the rebuild?

thanks
bob

I Have read a little about the injection pump itselfs.. I know is the same model for 230-250-280 and also know that use a cilinder for each injector. the problem is not the parts itselfs.. is to find someone who really knows what is going wrong and repair it.

I would be very glad if you give me some advice, I repeat, only owner, not crashed, very few used car...

I will try to take a pic from the injection pump itself but that will be next week.. thanks a lot.

Are you talking about the injection pump (on the engine) or the fuel pump (next to the gas tank)?

I have a New Old Stock original MB/Bosh equipment still in its box, never used, for sale if you need it.

It is the fuel pump next to the tank. I've got it off and taken apart and cleaned up. Right now I'm looking for the parts for a rebuild. I'm having trouble finding a place to buy them. I know George has a kit, but I can't seem to find his contact information.

Thanks
Bob
