What is the price of a hpfpupgrade from you if you import them then?

Have done a bit of number crunching for the duty and vat charges coming from the US including postage etc. Normal price is around £680 imported (for a stage 1 pump), I think I can retail them for around £575ish including VAT but would have to buy 5 of them at least, not too much of an issue as I want one on mine anyway
They also sell upgraded rail valves that can be set to 135, 145 or 155 bar.
They do offer a stage 2 pump which is recommended for big turbo engines, wouldn't imagine it's needed under 400bhp
Is there a part number for the new seals?
They upgrade their pumps with a custom seal, not OEM. It's another secondary seal that stop the oil mixing with the fuel, apparently it's a patented design so other fuel pumps can't use it.
