Fuel Filler

Finished off the Fuel Filler Neck and installed.

The Fuel Filler Tube is a shortened Holden OE VT Commodore Wagon Filler Tube.
The top half of the tube and its vent tubes are retained but cut just after the breather valve component.
A 45 degree 2" exhaust tube is joined between the filler tube and the tank inlet tube with Mackay rubber fuel 2" hose (Part Number CH5933).
The fuel pipe has been HPC coated for rust prevention.


Pedals

Still plodding along,
Made up Clutch, Brake and Accel Pedals over the last week plus took my annual anniversary pic....another year gone.

After mounting the original pedals, I felt they were too high at 230mm off the floor and i still hadn't bent them into position, the pad being under my toes when my foot was resting on the floor.
Bit of research and a look at a Tilton Racing setup i decided i would make new ones.
The main goals were to increase the space between the pedals, shift the pedal layout to the left about 50mm and lower the height by 25mm so the pedal pads were under the ball of my feet.



Built a 3D model in Inventor, then exported the DXF drawing and cut on the CNC.

Pic of the cut 8mm MS profile for the Brake Pedal, The original un-bent Brake Pedal in the back ground.
The smaller hole to the right is the pivot point, the larger hole is for the balance bar bush.



Pre-assembled before welding, machined the pivot tubes from solid stock on the lathe.

Also tilted the Pedal Pad slightly back so it was better presented to the foot angle.

Turned the pad side ways to suit OEM VZ HSV  Aluminium Style Pedal Pads.





Built the clutch pedal up the same way, Painted and assembled ready to install.



Pedals fitted with VZ HSV Commodore Pads.

Brake & Clutch Pad Part number: 92113883
Accelerator Pad Part Number: 92113881

Clutch Pedal on the left is same profile but from 6mm MS and less the Balance Bar Tube.




Accelerator Pedal Assembly.
The mechanism is an aftermarket LJ/LC Holden Torana cable conversion Kit KH004 from Rare Spares.
Modifications to this were shorten the Cable Pull Arm and weld a new 3 position Cable Pull Bracket on. (key point was to make sure sufficient arc rotation to open throttle bodies fully.
Bent the foot pedal arm over about 10mm and reassembled with the VZ Accel Pedal Pad to match the Brake and Clutch Pedal Pads.

Installed.
The CR chassis comes with the pedal support built in and has a Accel mount to suit Drive By Wire (DBW) pedal however I have installed aftermarket dual throttle bodies on the LS3 that require a cable pull activation method.
The original DBW mount has been removed from the pedal support.




After installing the pedals, I drilled a hole in the firewall and installed the Accelerator Cable.



Throttle Cable location at the top of the Footwell.
















On the other end of the cable.
Could not find a suitable Cable Bracket to mount to the Throttle Body, I wanted to integrate GM factory Cruise Control Cable but none of the commercial brackets had the suitable hole profile.
Another round of drawings, CNC time, a bit of vice bending and some paint and a custom 2mm MS bracket was created.

In the pic below, you can see the black Cable Bracket installed with:
Lokar 48" Accelerator Cable LK-XTC-1000HT48
1/4" Spherical Ball Joint with 1/4" female threaded end which suits the Lokar Cable End.
Holley Kickdown Stud #37-12 (has same cable pull end design to suit GMH OE Cruise Cable)
VZ Commodore Cruise Control Cable.
