Can someone tell me what size/thread type I need to look to replace the fitting that screws into the bottom of the fuel tank? I bought a stainless barb but the original is not pipe thread apparently. It looks more like a hydraulic fitting. What do I need to look for?
Thanks,
Are you referring to the filter and/or the hose that goes into it?
What part on this diagram?

That would be 584. I replaced the pump filter accumulator and all tubing up to the hard line. I have a hose for part 584 but there's no fitting but, the one I bought is NPT. I just wanted to be sure to get the right thing this time. Or is it easier to find the actual:"FUEL HOSE" ?
584 FUEL HOSE 001 A 11 647 015 75 - $28.28
SEE FIG. NO.:
FUEL HOSE
Replaced by: A 123 470 08 75 - A 11 647 023 75 - -
You will want to use the hose with fitting:

Normally we would say Mercedes only, but several here have suffered early failure of thecloth covered hose from mb. The cohline one above I would think a better choice.
As your car is from 1976, you should have the K-Jetronic system which uses the following hose : A1234700875 . Should be around $30 from the dealer. Or from FCP Euro or Autohaus:

Thanks, I don't want to have to do it over so I'll just get the right one.
