Between this and a single solenoid? I know, dumb question, but I just came across this for sale for cheap and was wondering if it works like a normal solenoid

 

looks like there is a T fitting between them. either use them as a 2 stage or one as a purge

 

What type of line do I run for the purge? That's what I am buying it for. Steelbraided? Or plastic type tubing?

 

it will need to be a hardline so it doesnt flop around when you purge and i dont think any plastic tube will hold up to ~1200 psi. purge kits are sold with a metal tube, replacement tubing is at the bottom of the page

Gotcha. Then just get a purge nozzle? Sorry, dumb questions, but I appreciate the help

 

just cut the tubing, no need for any type of nozzle...
