Using a straight AN6 to a 90 didn't provide any clearance to the firewall, so a 45 must be used as illustrated in the AeroVee manual. However, a 30 second operation to screw in the fitting turned into 30+ minutes as there was insufficient clearance when threading the 45 into the turbo body. Was unable to install an AN6 45 elbow without removing material from the turbo housing. Best tool for removing the majority of material was a Vixen file to take off the edge of the edge of the housing.
