Default Rover 75 CDTi fuel check valve (under fuel filter)

Hi All
I have a very slow diesel leak from the hose going to the front end of the fuel check valve, under(ish) the fuel filter. There's a jubilee clip on there so it looks like someone's had a go at a repair before.
I'm looking at replacing the hose as I'm thinking this is most likely the problem part but thinking I might replace the valve as well.
Is it generally the hose or the valve that's at fault?
Do folks replace the valve and what with?
I'm guessing the front end (with the metal ring) is the inlet?
What's the size of the fitting on the T-piece at the other end of the hose? Hopefully 8 mm.
That's a few questions but hopefully someone can help. Cheers.
Van

This is a pressure relief valve made by pierburg ,the last time I looked they were unobtainable and I had to settle for a second hand one ,but fortunately they rarely go wrong. Do not overtighten a jubilee clip they are quite delicate. 8mm is the pipe size.

Thanks Tony - looks like you are near me (when you're not in Spain) as I am in Highcliffe.
