When I originally configured the car, I intended to use a Tremec TKO 600 transmission. By the time I ordered the 347 from Blueprint they had replaced the TKO 600 with a Tremec TKX. I was pleased as the TKX is an improved version of the TKO 600 and Blueprint added a hydraulic clutch in place of the mechanical clutch of the 600. The downside of the change is that I needed rot swap out the mechanical clutch setup in the peddle box and replace it with a master cylinder. Fortunately, the peddle box had another position for a master cylinder.
I’d already created a two-reservoir setup for the brake lines and didn’t want to take that out to add a third reservoir for the hydraulic clutch fluid as it would also mean drilling a new hole in the footbox firewall for the reservoir hose. Below is the setup for the brake lines.
As such, I decided to create a second position for the hydraulic clutch fluid reservoir on the main firewall at the rear of the engine bay. I also decided to use stainless steel braided covered PTFE hose and bulkhead fitting rather than grommets as in the case for the brake line reservoir hoses.
The added master cylinder can be seen in the bottom of the photo. The line from the reservoir comes in to the top of the master cylinder; the line to the hydraulic clutch comes out of the right-hand-side of the master cylinder (a light blue fitting). The next photo shows the routing out side of the footbox. The line to the transmission goes to the transmission tunnel.
The line to the transmission goes to the transmission tunnel and is held in place with hose clamps.
The table below lists the fittings for the supply and transmission segments of the setup. Note: 1) all fittings are AN 4; 2) the supply and hydraulic clutch ‘sides’ use different PTFE hose. Both are for use with hydraulic fluids but the 3260-4 hose is for high pressure use.
