I am trying to have some work done on my 1983 380 SEL and I am questioning the estimated hours of labor that the local repair shop (MB specialists) are giving me:

*** 1 hour to put a fuel pump check valve on. (this seems like a 20 min. job)

***5 to 5.5 hrs to have the rear brake lines replaced. (this seems like 3 to 3.5 hours should cover it)

I am also looking to replace all of the high pressure fuel lines, and the one fitted line (pump to line). the car already had the tank to pump line replaced. How many labor hours involved??

Maybe I am underestimating the time involved in these repairs? Any opinions?

THANKS!!
