W126, BENZ AID - COMMON QUESTIONS AND ANSWERS

1988 560sl
I go about 15 miles and black smokes starts and gets progressively worse,
and shuts off. About 2 or 3 minutes I t does the same thing again.
have cleaned fuel system, new fuel pump and new air filter.
I need some help on this one.

I'm struggling with the decision over buying the injector rebuild kit (with monarchs) or simply buying the already rebuilt monarchs and returning my cores. I know some of you have gone down this road and I would appreciate any comments and/or advice you could give.
My worry with doing it myself has to do with leaks. It seems like competent folks who are following the procedures are still getting leaks. Has anyone experienced leak problems with the MB Source rebuild injectors?
Thanks and I'm going to make a decision sometime in the coming 2 weeks.

Hi,

I need to know the size of a fuel hose.

It's the clear fuel hose that returns fuel from the injector pump to the top of the fuel filter. The barb connection on top of the fuel filter and the banjo/barb fitting on the back side of the I.P.looks to be slightly smaller the the other banjo/barb fittings on the fuel filter. I have 5/16 hose on all my other banjo fittings and would think it would be the same size, but it looks smaller.

Hi Everyone,

I just finished fixing one problem only to get myself into another :-). I tried to install some of the new monark nozzles from mercedessource. I tried to be very careful and clean when reassembling the injectors after replacing the nozzles and thoroughly lapped all the mating surfaces with fine sand paper as described in the guide.

One thing I was not able to figure out is how to remove the old crush washers from the engine to replace them with new ones. Because of this I left them there. Any tips on how to remove these would be much appreciated as they seem pretty stuck in there and there were no hints in the manual I received.
