Changes to 05 Duramax?

I just bought a 2005 Silverado with the new LLY Duramax. Does anyone know if there are any changes made to the newer motor that would prevent it from rumming on B100 or blends? Just curious if there was a change in injectors or pressures. I am currently building my own processor using ideas from a couple of differnt members. Thanks John

I am also going to buy a 2005 Silverado Duramax. Medicnovo have you tried running biodiesel in your new truck yet? If you have I would be interested in hearing your remarks. Thanks

i too would like to know,  i think the thread is dead

Answer:

Use 100% BIO / B100 in all 2001-2007 GM  Chevy GMC Duramax trucks without any problems.

Need to replace the fuel filter housing with the one at Dmaxwrenchkit.com.

Need to replace the engine hoses with the ones at Dmaxwrenchkit.com.

I've been using my brew in my 04 sierra for over 100,000 miles. (now has 185,000 mi) Didn't have to change the fuel filter housing or any hoses. Just recently had new injectors installed. Really don't know if BD was the cause. 1 failed, so I changed them all.       No changes that I know of in the 05.  Just the placement of the glow plugs. Maybe a little more Hp.    Duramax seems to like the biodiesel. (Quieter)    I run B30 all year.    

I run B20 in my 2004.5 LLY in the summer and B5-10 in the winter. One thing I will say is that if you live in a colder climate common rail injected motors DO NOT like thick fuel. It will trip all sorts of codes because of the fuel's viscosity. Ask me how I know this, lol.
