Where can I find these parts for my 1990 420SEL?
 

Recently my 90' 420sel began leaking fuel at one of the fittings on the fuel pump assembly so I took the whole thing off the car and decided I'm just going to replace everything because it was all so rusted away. While disassembling the whole assembly, the line that comes out of the second fuel pump and connects to the inlet of the fuel filter broke because it was just so rusted. This line also connects to the accumulator. My only issue is I can not seem to find that part anywhere and i'd really like to get my car back on the road. I also need a new bracket that holds fuel pumps, filter and accumulator but I can not seem to find that either. If anyone has any ideas, has the parts, or knows where to get these parts please let me know!! Thank you!

Some parts are available with the site sponsors

I don't know if they are what you want though.

Ideally you need to get yourself on to EPC => www.startekinfo.com

EPC is free for US residents if you are willing to confirm your residency by giving your credit card details. Make sure you just get EPC and not WIS - WIS is very expensive and not free!

Once you have the part numbers you stand a better chance getting what you need.

Alternatively you can find information via other sites that give out part numbers such as this one =>

My experience of these parts is that they are seriously expensive. Good quality second hand is often a good alternative. I suggest you do a WTB advert on this forum if you want to go down that route.
