It was Erron Spalsbury that built the reservoir on his vent.... Ran a hose up the firewall and used a clutch fluid reservoir.
I cut off the factory vent and used the base of it for a grommet, bent up a piece of steel brake line to route around the axle, and connected that to a rubber hose running up the firewall for the vent. I don't often run it over 100 MPH, mostly the occasional pull to redline in third while tuning, but I haven't pushed any fluid since I extended the vent.
Edit: I knew I had a pic somewhere....
