I used -6 hose throughout the bay on mine, chopped the 2 metal pipes off just under the bulhead and used 2 jubilee clips on each one to secure the quip onto the old pipes which worked fine.
Fuel regulator i also just jubilee clipped as it's not really seen....i had a -6 union welded onto the fuel rail though and bought a tight 90 degree bend for that and used a sytec fuel filter with straight aeroquip unions. Did end up costing a fair old whack for what it was but looks soo good !!
I bought all mine from 'merlin motorsport' as they're just up the road from me and keep loads in stock!
You can just see the fitting on the fuel rail and the filter on the rhs obviously...
