To all MB Techies...

I have a 1991 300SEL (126 chassis/103 engine. I need to change the fuel pump and would like to save a few bucks. I have the service CD but it does not seem to cover that topic. Where is the fuel pump located? How do I change it out? All help will greatly be appreciated. I am an engineer but a novice mechanic. Is this a pproject that I can tackle??

Thanks.
