A ray of hope for my 300E. New fuel regulator!

[Cap'n Carageous]

Ever since I reworked the cylinder head on my 89 300E, my gas mileage went down sharply. A couple of months ago it went down to 10 MPG so I just parked it. I suspected part of the problem was the fuel pressure regulator. I just didn't want to throw another $200+ at it without being sure. Well, last Thursday I got lucky and found a good used one from a local independant MB tech. He made me a good deal and said if it didn't work to bring it back. My mileage has more than doubled and as soon as I can fix my intermittant shortage that kicks the CIS-E into 'open loop', I should have a good running engine again!
