I now have the bottom hose all cut to size and fitted and im just waiting for a hose joiner to come from Samco so i can fit the top hose. As i needed to extend the hose im using a hose joiner that takes a 1/8th NTP fitting as i have found a cool fan cotroller from Revotec (http://www.revotec.com/acatalog/EFC_Hose_Fitting.html#aEFCHOSE) it fits into the joiner (or you can get one already in the joiner) and it will control the fan temperature without having one of those ones that fits into the hose where it goes onto the radiator as they always seem to leak 😉
Once i have the joiner the top hose will go on and then all i need is to get the radiator brackets welded on and that’s the cooling all sorted out.
