local mb dealer. i made an ass of myself. changed glow plugs on 'blue'. an 83 240d with you-shift-tranny. anywho, as anyone who has changed out glow plugs knows, on this or perhaps any 123, the access is limited. wish for smaller hands and a bigger.... whatever. one of the fuel return lines needed attention. the quote. $16 and change for a meter. my recollection, erroneous, $3 or $4 the meter. *****ed. nothing serious. after apology on my part - $13 a meter. my goodness. fiber/rubber hose. a meter. $13. yes, i know. the going rate. seems obscene. and now another round! enjoy.
