Hard Brake Lines

I decided to rework the brake lines from the master cylinder to the rear calipers using Cunifer lines and AN fittings. I bought a Ridgid 37 degree flaring tool, which worked great. I ran the lines inside the car all the way to a point directly above the rear calipers, using a tee mounted where the rear seats used to be.

Oil Sensors


I wanted to install new Autometer gauges instead of the crappy stock gauges, but the stock senders are 10mm thread while Autometer use 1/8-NPT. So I blanked off two of the ports on the oil filter housing with M10x1mm bolts and copper crush washers. I redrilled and tapped the third port to accept a 1/4-NPT to 1/8-NPT bushing, which I installed with a little JB weld to make sure it never comes out of the soft aluminum housing. The autometer sensor screws right into the bushing. I've heard the stock sensors (low & high pressure switches and oil temp sender) are capable of blowing out and causing a mini oil geyser, so I'm happy to have got rid of them.

Racing Radiator


I managed to poke a hole in the stock radiator, so that was a good excuse to install a proper all-aluminum racing radiator. I found an Afco "Scirocco style" radiator at Summit Racing that fits perfectly. The outlets were the wrong size though, so I had to make adapters for the upper and lower radiator hoses.

Oil Cooler


This shows the oil feed that comes from the oil pump, coming out through the adapter plate, into the external oil
cooler, through the brass one-way valve, and into the engine. The disconnected port on the tee connects to the line to the accusump. The one-way valve forces the accusump to discharge into the engine and not back through the oil cooler and oil pump.

The lower picture shows the oil line that runs through the car to the accusump, you can see the manual oil valve, and the thinner braided line goes to the oil pressure gauge.

Accusump Oil Pressure Accumulator


Installing an accusump to protect the new engine from oil starvation in the corners. I located it at the rear of the car, just forward of the fuel cell bulkhead. This car needs all the rear-weight it can get.
