1 x SE462RH. Our special hose we developed to fit later big bore design,  Jaguar Saloon waterpumps that kick out sideways from the engine block (not straight down as the normal XK140/ XK150 pump does). The hose reduces down to fit straight onto the XK standard diameter under chassis radiator pipe ( on XK120 it drops straight onto the rad outlet). This hose is still very popular with racers running various  later waterpumps in their XKs and has extra length at each end so it can be cut down as necessary.
