Yanmar YSB12 diesel fuel leaking out from the injector pump.

Hi everyone,

I'm still getting air in the engin after 4 or 5 hrs of engin running. After changing all the hoses and 2 new racor filters 10 and 2 microns also a new elctric fuel pump Airtex E3887. I can not figure it out where the air can sneak in the engin?

I finally found the culprit ----- > By turning on just the electric fuel pump alone without cranking the engin, I noticed there's diesel fuel leaking out drop by drop from my Injector Pump.

I'm seeking advise on how to tackle this problem.Attachment 84403

Thanks
Mellieha
