Re: Fuel Injector Pump leaking

There was a degradation in performance. I knew air was being sucked in but could not find the source.
I just went through something similar this spring. My motor was taking a long time to get started. It was losing its fuel prime. I also had fuel weeping around the top of the injector pump. It turned out to be the o-rings around the fuel injector nozzles. I was able to repair it without removing the pump by just pulling each fuel injector barrel, replacing the o-ring and a little copper washer gasket. I got lucky. We have a very knowledgeable diesel pump repair shop in the area who told me it was a common problem with old Volvo diesels.
