I just purchased my first Duramax yesterday. It's used, a 2001 2500HD with the Allison. Just wondering if there are any common problems/concerns I should be aware of?


TIA,

The main problem is the fuel filter system design. It would be time well spent to make sure your fuel filter is clean. There is a good forum topic called "Ask the Techs" where a thread describes how to quickly change the fuel filter, written by dmaxalliTech.


After that consider adding a secondary fuel filter. There are several secondary filter choices out there. You could check poster's signatures for solutions. This site also has a forum topic specifically on fuel filters.


And, if you arent already doing so, look into using fuel additives to keep the fuel system clean of water, bacteria, and rust.

Thanks for the quick response. No, I'm not using a fuel additive now but I'll see what's available tomorrow.


Thanks again!
