W210 E300TD Fuel Pump Help, I'm an idiot!!!!!!! - PeachParts Mercedes-Benz Forum

Hi Fellow Members

Firstly excuse me if I haven't made my introductions in the introduction area, I can't seem to find it!!!

I have a problem and was hoping that someone could help me, as I have been searching google for the last half an hour, and various forums, and can't seem to find the answer.

I was changing the delivery valve seals on my 1998 E300TD, and whilst taking Number 2 injector pipe off the pump, I have stupidly snapped the rear (of the 2) plastic pipe and plastic attachment to the pump on the right of where the injectors/deliver valves attach, black pastic connection with white clip holding it on. I can't even start to tell you how stupid I feel and how annoyed I am with myself.

What do I do now? Is this a part I can order by itself, if so, does anyone know the part number? I don't even know what the part is called, which is probably part of my problem when it comes to searching the net/forums.

Any help would be greatly appreciated as at the moment, I am feeling extremely low, stupid, etc. etc.

Thanks in anticipation of any help at all.

All the best

Mark

Welcome to the best forum for support on our diesel vehicles!
I'll do a little research on here for you, but I'm sure others who have faced this issue will chime in shortly!

Sounds like you broke the fuel line leaning from the pre-filter to the shut off valve.

They are ~$10 each at the dealer. Each is unique. Push the white horseshoe tightly in to remove. It is a spreader to release the clips holding it on.

Its either line 2 or 5 in the diagram.

From what I have read the plastic claps get brittle with age and crack easily. So it is a common problem for them to break when removed.

Let us know how the job of changing the Delivery Valve Seals come out.
Below are the 2 areas were some of ther repair stuff is in some sort of order:

Guys

Thanks very much for your advices, I really appreciate it. Turned out I'd managed to snap the hard fuel line carrier from the stop solenoid to the bottom of the pre-filter, which as stated could be bought as a complete unit, thank goodness, and only cost me £7 from the local dealers. To be fair to them - Mercedes Benz Bridgend - were absolutely brilliant, they spent an age with me going through schematics until we were both sure we'd got the right bit.

I followed PoDs guide to changing the delivery valve seals here - http://www.peachparts.com/shopforum/showthread.php?t=211801 - and to be honest, it was brilliant. I wish I hadn't ignored his tip about taking the fuel lines off 6 to 1, this is where I went wrong and hence my faux pas. Only thing I'd say if I was doing it again, I would probably have taken the hard fuel lines off the stop solenoid as well to access sakes.

On the upside, it's been in the 70s today, and I'm well happy with the finished result.

Cheers again to all.
