Good video. I'm not sure my DEF pump should be cleaned or replaced. Truck have 700 000 miles.I bought truck with 437 000 and never change DEF pump. I getting DEF quality us not good even if I use best DEF.I change DEF quality sensor and planing to change DEF pump. Not sure if is good idea to just clean DEF pump becouse I'm sure I didn't change DEF pump 365 000 miles and don't know if ever before been changed.

If you don't see any leaks outside the pump , I don't see why to change it . All it does is pumping the fluid to the def injector. Even if I had those problems , I never got the quality issue. If you fuel the def tank all the way , dose it put you for regen not long after? In my case , after I fixed the leak problem , I never had the regen problem after making my def tank full. I don't think you got quality issue from the pump , I had this problem from the wires touching on the side of the def tank , volvo have big issue with this problem. They rubbing on the metal... also check if your def injector is not cloged . With so many miles , may want to replace the filter of def . Is expensive at dealer (ab . 100$ ) , pls don't go with aftermarket , you ll have problems , the rings don't seal right , and you ll have leaks as soon you start the truck

How long would you say it took start to finish?

Usually dosen t suppose to take that long.. it s the problems you may run into.. such broken /frozen / stripped/ cristalized bolts, or the line wouldn't disconect because of the broken clip or build-up rust ... if you don t have those problems, you are in luck, and everything would go smoothly in probably 3 - 4 h . If you just replacing the all assambly (not rebuilding), I'd probably give it 1-2 h - hopefully no lines will be hard to remove.
