I have installed an aluminium ast on my FD.
My question is, is it supposed to be installed somewhere so that the inlet of the ast is above the nipple on the radiator filler neck?

From what I understand it should be so the air bubbles can float up to the ast. But I have seen a few setups where the ast is lower and, or the hose goes down and then up.

Just need confirmation as it doesn't look that nice having it so high in the bay almost hitting the bonnet.

Cheers
