fuel pressure regulators 1985 380SL
I have been troubleshooting a rough idle and intermittent hesitation when accelerating cold and I discovered fuel leaking out of a fuel pressure regulator, which this car seems to have two of. I don't see anything about these when looking at the Bosch CIS K-jetronic with Lambda information and if i followed the fuel lines correctly it looks like they are both in line with the frequency valve. What is the purpose of these exactly? Obviously I need to replace this regulator that is leaking but I was wondering if someone point me in the direction to some info on this part of the system that would be great. Quite pricey these guys seem to be too. Thanks.
