    Older ISX, in a 2003 9400i. This is the last of my leaks! Didn’t even know it was leaking until I got all the oil leaks fixed.

    it’s leaking from the driver side, seems like mostly when it’s shut off, I assume the Fuel distribution “thingy” don’t know the name. The triangular piece was leaking but I replaced gaskets in it and it’s good. I’m not sure if it’s the solenoids leaking or my make feed portion where the line comes in. Is there a rebuild kit for this thing? I’d attach a few pics but I’m not sure how! Do I need a hosting site to post pics here?

    You can see a drip in this one. It looks like a few of the solenoids are leaking. I don’t know which is fuel though

    Those 4 solenoids are called metering valves. Cummins makes a kit that has oring and plate. (1) Do one at a time. Inside valves and outside valves look the same, but are different part numbers. (2) when you take them off, parts will "explode" like jack in the box. Put them back in EXACT ORDER they came out.

    Yup........

    Inside actuators are for fuel injection timing.
    Outside actuators are metering or quantity of the fuel injected.

    Not sure about yours, but I have a 2011 ISX 15 and my fuel pump is two pieces, the head and the body between both is a gasket. I just ordered the parts to rebuild the head which includes the tappets, barrel and plungers and the gasket. Youtube has videos and I heard on at least one that they will leak fuel. Try the QuickServeMobile app it will give you part numbers and you can buy on Shopcummins.com
