I tried Pirtek myself, and they could supply hosing no problem. However the only banjo bolts they had were too big. I still have them sitting spare as they dont do refunds. £12 odd as well, just for the banjo - the bolt was arounf £9 extra!!! Only thing they offered was to shave the head of the bolt down for me but that didn't work either as it was still too wide with the banjo to fit between the manifold and turbo housing.
