They are only open to walk-in customers on Saturdays (until lunchtime). Moquip is their own manufactured fittings.
You can use the FC333 hose but it will emit fuel vapour after a while and basically you will smell petrol all the time, not so bad if run underneath the car but not ideal. If you want to do it properly, use TFE lined hose, I recommend the "progold" hose and fittings, the hose itself is MUCH more flexible than over types of hose which helps on installation. Get all the part numbers from the catalogue you downloaded and then call Rally Design as they sell the same stuff ALOT cheaper
