|Photo DIY- M111 Fuel Pressure Regulator R/R|
I was out doing my "Full-Body-Cavity" Service on Mother-in-Law's W202.
Because of a "Difficult-Cold-Starting" Condition, requiring a few Cranks in order to achieve a "First Start of the Day", I thought maybe the Fuel Pressure Regulator was at fault.
Although I saw NO Fuel coming out of the Vacuum Fitting? I still was convinced the Regulator may be bad. I had a similar situation on a M119 Engine... "Tested" Fine, but was still bad!!
For $30 bucks? I did not monkey-around with Pressure Testing With & Without Vacuum application.... Simply changed it out! 2 Minute Job.
Now?? Cold-Start is PUUUUURFECT!!
