Installing the Intake Duct (Response, Bigfoot, Vanguard2 & Vanguard Models)
1. Install the intake duct inserting it closest to the front of the vehicle. This is where the
widest available area allows it to be pushed into the vehicle. Position it in front of the
engine flywheel fan assembly.
2. Fasten the intake duct to the hood support assembly using the spacers and 2 fasten-
ers.
On 6x6 Vanguards manufactured prior to S8131, reconnect the extension spring from the
intake duct to the molly hook on the lower body.
3. Secure the fuel line to the nylon clips at the intake duct.
Removing the Intake Duct (Conquest Models)
To remove the intake duct on Conquest models, the upper body must be split from the
lower body.
1. Peel off the rubber bumper assembly
from the vehicle. You need only strip it
off far enough off to drill out the speci-
fied rivets.
2. Using a 3/16" drill bit, remove the riv-
ets starting from the front center of the
vehicle to approximately the dash area.

3. Separate the upper and lower body, sup-
porting it apart using a couple of 2x4 pieces of wood.
4. Locate the fasteners securing the intake duct to the lower body and remove.
5. Raise the upper body from the lower high enough to accommodate the height of the
duct as you pull it out from between the two.

Conquest models maufactured prior to CB17117 utilize a sheet metal style intake duct.
Intake ducts on Models manufactured from the above serial number, are made of moulded
plastic.
Earlier sheet metal ducts are no longer available, but the newer style is fully
exchangeable. However, optional parts are necessary when ordering your replacement.
