Hello, My 1995 C-320 Perkins M-30 has developed a new quirk: it starts right up and dies suddenly after a few seconds. It will restart with a bit of cranking (c. 5 seconds). I’ve bled the system, tightened all hose clamps, looked for any diesel weeps. My thought is a small air leak, but can’t locate it. Any thoughts? Thanks. Lou Spitz #195 ‘Merry Chase'
