Some probably most Cummins 6BT series engines have a fuel block which as I understand it is a block of metal with channels bored into it with fittings where fuel enters and exits the engine. It also has ports for fitting fuel and oil pressure gauges and probably some other test equipment. There appears to be up to 8 ports and in my case several are plugged because they are not needed. This engine is a reman, a year and a half old. Fuel has been leaking from one of the unused and plugged ports since it was installed. I didn't realize fuel was coming from one of these ports until I finally decided to hire Cummins to fix the fuel leak knowing I still had 6 months of warranty left.
Because this is a reman long block engine several items were taken from the old or core engine including the starter and fuel block. So the fuel block because it is not part of the reman is not covered under warranty. The location of the fuel leak plug is very difficult to get to requiring a partial disassembly of the engine, mainly removal of the after-cooler and probably the fuel cooler. Cummins is estimating 8 hrs to fix this which is nearing $1000.
I have removed both the fuel cooler and after-cooler several times and it is a real pain. 8 hrs is a bit of a stretch but it is a pain. The boat is 1000 miles from home and the mechanic that installed the engine is not available that far away. I have very limited time to work on the boat and with a car rental for a couple of days it would cost me a couple of hundred bucks if I do it my self, which I just really don't have the time to do. On top of that I just recently developed a pinched nerve which makes it very painful to reach down into the engine. I'm hopeful the pinch nerve pain goes away soon, most do.
I'm just ranting but a lesson learned. I should have fixed the fuel leak right after I noticed it. We left on an extended cruise and didn't want to wait.
