Still struggling with T peace cooler pipe

Can anyone help with somewhere to get T-Pipe cooler hose onto of rocker cover please? No one seems to have and my mechanic failed too

Not 100% sure this is the right part so might be worth a phone call…

Have you tried a VW dealer as that's where I got mine from but it was a few years ago.

Mark, you star thankyou appreciate help, I have spoken to Heritage and tried to order the hoses and radiator but took ages to come back and told me they didn't do this hose but pretty sure what you found will do job!
We deal with several VW Dealers, will send over picture to one now and try my luck……

Thankyou.
