Same mod as Dave but i use a bulk head fitting that has longer threads and the two taper seats meet as per bleed nipple and seal. The other mod i have done for the rally car is fit a https://www.staubli.com/en-us/connec...torsports-cbr/ this allows you to unplug the pipe and leave slave mounted to engine. The next mod i have done is fit another bulkhead fitting to the bleed nipple port and using aeroquip pipe is mount the bleed nipple on the bulkhead near where a coil would normally sit this makes bleeding a lot easier as access to the bleed nipple is easier.
