[W126 Coupe] 1991 560 SEC Fuel Pump Replacement

[Markus Meyer]

Henry,

I've done my 87 SEC and 89 SEL.  The "ends" of the fuel pumps are check
valves that screw on there, I don't believe they come with the new ones.
You can take them off your old ones and reuse them.  Do the pump bodies
otherwise look the same?
