JD 4024 Doosan compressor
I have a Doosan compressor powered by a JD 4024 with only 1900 hrs. On a test run, the sump filled with fuel up to the dip stick. I was wondering what could be causing this to happen.

On that engine there are 4 individual fuel pumps built into the engine, one for each cylinder and they are operated off cam shaft. They are a SOB to replace and are supposed to be done in sets. I don't know how you would test to know which one would be the culprit.

Here is a video showing a little bit of it.

Well, if it’s leaking that bad..
U could remove the steel line and put an air hose to the pump and injectors and listen for a hiss..
Just a thought..

You've seen more pumps than most. What's your opinion on the JD 4024 repair?

Very expensive to repair..
The fuel system WILL NOT TOLERATE ANY WATER what so ever..
