Looking at the diagram in the TR4A spare pars catalogue ( same heater)
it would seem that the longer pipe , is at the top and is the return
port on the rad. Inlet is definitely the bottom. As far as function is
concerned it wouldn't matter . The direction of water through and air
across the core would be reversed but it's just a heater core. The real
difference would be in how the hoses lined up in cramped quarters. The
pic definitely shows longer at the top
