Vauxhall Cresta PB 3.3 fuel running temps hot running problems.

As title this is first of 2 for this car, trying to solve the 'vapour lock' which i get with this car it will not start when hot cool for 30 mins and away it will go without fail.
I had similar problem with Cresta Pa, which hopefully i have solved 'video on channel' but forgot to take temp reading prior to work.
