Bobcat 643 leaking diesel

Hey guys, got myself a bobcat 643 with a Kubota d1402 motor. Runs great although it leaks diesel everywhere! seems like it is coming from the 3 lines that go to the fuel pump. are there O-rings in there that need changing? if so where can i source them from?/ Much appreciated Cheers! Dave

when mine leaked the hoses were dry rotted, just replaced them.

Are you talking about the 3 bits that screw into the injector pump that the injector lines screw on to?
You some times get fuel around the base of these lines. There are O rings under here, but be warned, you must be careful removing these parts as the parts under them are all timed.

yeh it looks like its leaking from where the 3 lines screw onto the fittings that screw into the fuel pump? if that makes sense?

That makes sense. Remove the tube lines and then remove the delivery nozzles, but as i said earlier. Do not remove any parts under this nozzle. There are one way valves and springs, go no deeper than that.
With them out, remove and replace the Orings and you shoudl be leak free, i have done this a few times before. They get hard over time and start leaking.
