    Hi there,
    My twin Cummins 6bta 370hp engines have a few fuel leak which I’m working on, the worst being around the fuel injection pump return pipe where it connects to the return hose going to the fuel cooler. Can somebody tell me what thread the return hose is where it connect to the return pipe from the inj pump. I have renewed the O ring but the threads are but of a mess.
    Thanks.
