Reliant engine cooling hose.

I know Ive read about his somewhere on here,(and commented myself on it)..but cant find it!...............
 The hose that runs from the water pump to the rear of the head is it necessary? Andy ,have you used this on previous builds,and if not ,did it have any bad effect without it?

Differences of opinion on that one.
Ska Man ran without it on his Reliant I think. Muffin used a couple of brass 90 degree plumbing fittings to keep the pipe close to the cylinder head.
I haven't tried without it yet, but have been wondering whether it would be O.K too.

In the car it is for the Heater Matrix. I've seen em run with and without the hose connected on a trike but would advise you have a temp guage fitted
