If you are after new ones, CarParts4Less sell them quite cheap. E.G. I've just bought the following - they are for my PH2 175 so very sure they don't fit yours but as an example: Goodridge SRN0615-4C (Stainless Steel Fittings) - Typical price ~£75 online http://www.carparts4less.co.uk/search/972740290/p/home - £63.84 Less the 12% bank holiday discount = £56.18. Can't find them any less than that. EuroCarParts have them at £80.39 - http://www.eurocarparts.com/search/972740290 - but have them listed as "performance" so none of their promo codes apply. Same trick applies to all the powerflex stuff they sell - just bought a whole bunch of it via CarParts4Less for 30% off the best price I could find online.
Cheers for that mate but according to their site they don't fit my car. I'm not sure what the difference is between ph1 & ph2 lines.
