View Full Version : MD 67 fuel pump problem

03-27-2009, 11:37 AM
"My MD67 may need the fuel pump rebuilt but the shop that rebuilt it twice before says they can't do it now because of trouble locating parts. I just spent $600 to have new nozzles put on the injectors (they tested weak) and the engine is still performing poorly-- it idles o.k. and starts easy, but starts missing erratically in rpm's over 1000. Will test feed pressure and relief valve today, but after that (?).
I need to know what Bosch pump I can use on this engine to replace the CAV#NL6F75/91, centrifical governor#GRV,WB1 or 2. The CAV pump or parts do not seem to be out there anymore."
