[QUOTE=bostonmish;2400279]My car has developed a bog down, stall, wait, restart, repeat condition which sounds exactly like a symptom of rust contamination in the fuel tank.

which engine? Excellent idea to clean out a old rusty tank but its also possible the fault is elsewhere else .

It's an M117.985 '79 450SLC I am pretty far along the diagnosis path, eliminating all other possible contenders. Here is some background: Flushing the Fuel Distributor

I should have made my original question less vague, but what I am really after is whether or not the SLC fuel tanks require anything special in the cleaning process.

I've looked at the three stage (flush, derust, recoat) approach and will likely try it. ...just curious if anyone has run into anything out of the ordinary when treating the R107 tanks.
