Re: Perkins 4-108 Fuel Injector Pump Leak

but due to access it took a while to figure out this was from the top of the pump
around the throttle I believe.
I was reading around and it was suggested that this might be caused by a blocked return line
so I pulled the line
off and put a wire through it. Seemed like I hit a block once that I pushed through. I started the diesel and the line
ran free and when I reconnected it to the tank it appeared that the fuel
injector wasn't leaking as much.
So now I'm wondering about the difficulty and any problems involved in replacing the seals/gaskets on this hydraulic pump
. Does anyone have some guidance on this?
An injector shouldn't be leaking at all. Regarding the Injection Pump
, you might want to read through this thread: DIY Injection Pump Rebuild - Cruisers & Sailing Forums
. Its a bit long but filled with information. Also, check your oil for level and particularly for evidence of fuel
