I think there is. Look at attached photo. It runs down towards the cold water feed to tank.Doesn't seem to be any mods to the vent and pump attachment., the vent is a continuation of the boiler flow pipe so will be quite hot for a portion as this is where the expansion takes place.
I would ensure that the vent is clear right up to where its bent over the F&E tank, maybe just blow down it (boiler off) or stick a hose in it and overflow the F&E tank for a few minutes.
Did you look at the F&E tank again and try and see if there is another pipe opposite to the cold feed at the other side of the tank bottom? or maybe its a electrical wire.
One other thing
