Installed the reservoir for the brake fluid on the firewall. The connection on the bottom of the reservoir is a 1/8" NPT thread. I had some connectors modified to 1/8" NPT at the factory earlier this year. I'm sure the supplied connectors are 1/8" BSP thread. The brake valve also has 1/8" NPT threads, so I need another four modified connectors. ( I only have two 1/8" NPTremaining ).
