Can Bio Diesel be used on an LB7?

Yes, Whay Kind Are You Looking To Run. I Have Abuddy Who Makes His On, Then Charges Me $1.00 A Gallon.i Run 100 Percent In The Summer Time And 50-50 In The Winter Time, Do To The Fact It Gells At 35 Degrees . The Only Thing I Did Was I Am Running Another Fuel Filter Rihgt After The Fuel Tank. It Is Another Filter With Water Sep On It, Due To The Fuels Cleaning Ability. Hope This Helps.

I really wanna get into making Bio, Iv heard the gel point is higher than that on 100%... what controls the point it gel's at?

Also, it doesnt damage any part of the fuel system in any way does it? Noone that you know of has had any problems with their fuel gauge not working correctly or anything?

No I Havent Had Any Problems And My Buddys Havent Had Any. I Am The Only One Running A Duramax. The Other Two Have Cummins. I Dont Know What Controls The Gel Point, I Can Ask My Buddy. As Far As The Gel Point Being Higher, I Think That Is On The Bio Coming From A Pump. We Test Every Batch Me Make And They All Come Out About 35 To 37 Degrees. Just So You Know When It Hits About 40 Degrees We Start To Run 50-50.to Answer Your ? About Damage To The Fuel System Is Maybe. I Ran 100% For Three Months And My Buddy Asked If I Had Checked My Fuel Filter I Said No, He Said Check It. I Did And Changed It Out. It Was Full Of Junk. So If You Make Your Own I Would Run Another Fuel Filter From The Tank To The Engine. The Only Thing About Bio Is That It Is A Awesome Cleaner, So Unlike The Fuel You Get From The Pump Which Is Not Clean. The Bio Will Clean Your Fuel System Which In Turn Might Cause Your Fuel Filter To Clog. Hope This Helps You Out Any Other ? Just Give My A Shout And If I Cant Answer My Buddy Can.

I saw an add for a kit to make it in one of my diesel magazines and it really struck my interest. Any idea on a rough cost for the equipment to do this. Is it really time consuming?
