I'll probably get flamed for this (ha!) but I run tight fitting rubber
fuel line and fuel line clamps after my regulator. The pressure after
the regulator is really low - like 2 lbs of pressure - so you don't
need any sort of pressure fittings. I have a 12V fridge so I only need
one line after the regulator and I sheathed the hose in another bit of
larger hose where it passes through the body to protect it. Much
easier to work with than copper line and after two plus years, its
never leaked. I would keep t-connections under the van. Good idea
about the solenoid.
