Yesterday the new hoses arrived from JS Performance. The top hose is the standard manta one, but the bottom hose has been enlarged on the bottom part to fit the Summit Racing radiator. I have also got a set of heater hoses from them as well. these are not specially made for the A series, but are Lotus Cortina ones as they are the right length and have the 90 degrees set in the right place as i will be routing them across and down the other side of the engine as with all the injection and throttle bodies on the other side there just isn’t room!
