took the hose of it was slightly split on the inside, just cut it shorter and its fine.
the hose im using is plastic not teflon lined, its still "proper" hose and suits the application. It doesnt use a any threaded ends though but isnt necessary anyway.
I was sort of hoping that would be related to the over fueling issue, ill try replace the FPR now there's a weird noise coming from there during ignition..
