Hi Guys
Probably been through this one 1000 times before so might be an easy one hopefully. Unfortunately no manuals were supplied with the unit when we bought it so here I am.
D333 23C698 4.75" bore powered generator. Works beautiful, took it up to 90-95% load going perfect clean exhaust too. Anyway noticed the drain tube originating from the fuel pump was dripping/running diesel so I guess it's time to pull something apart, i'm guessing going to need to replace some seals possibly?
See drain tube in question:

Yes, leaking from the seal cavity between the two 4S7756 seals and you will also need a 7S2374 gasket. Plus a few more...

Testimonials

"I also joined a year ago. had been on here a couple of times as a non-member and found the info very helpful so I got a one year subscription (not very expensive at all) to try it out. I really like all the resources on here so I just got a three year. I think its a very small price for what you can get out of this site."
