I have a 2005 Dodge Dually, and I am considering trying Bio Diesel, the
drawback is the biodiesel may cleanout buildup in the tank and clog the
fuel filter. How much of a pain in the ass is it to change the filter.
In response to previous Posts I get between 17.5 and 18.5 Mpg running
down the hiway, and about 12 pulling my 3 Horse w/living quarters
gooseneck trailer fully loaded. I am also able to accelerate going up
the steepest grades.. Big change from my 2003 2500 Dodge.
Any insight to changing out the fuel filter would be greatly
Thanks in advance
Very simple. It's in a canister, located on the driver's side of the
engine, back near the firewall. It's got a black plastic cap on it. You'll
need a 1-1/8" socket to fit the hex head on the cap. Unscrew the cap, and
lift it (with filter attached) out. With a drain pan under the engine, flip
the yellow lever at the bottom of the canister. This will drain the
canister of fuel. Spray down the inside with brake cleaner, which will also
drain out. Close the drain, remove the old filter from the cap, put the new
filter on, remove the old O-ring from the cap, and put the new one (comes
with the new filter) on. Lubricate the O-ring with a little diesel fuel,
replace the asembly, and tighten the cap just until it bottoms out on the
Use only Fleetguard fuel filters, available either locally from a
Cummins/Fleetguard dealer, or online at http://www.genosgarage.com . Don't
pay twice the price for the same filter at the Dodge dealer.
