Mine and the other ones I've seen just use flexible hose. If you mount the cooler behind the passenger scoope, running the hose is basic. Its really not a hard install. If you're concerned, I'll take a picture of it to show you how I did it...no VFAQs this time. And another thing, now that it is getting colder, is your fuel pressure too high when you start the car up cold. If its 35F outside and the car has been sitting all night, my fuel pressure will be like 60+ psi until things fully warm up. When the whole engine bay heats up, the pressure goes back down to 50 psi. I moved my FPR next to the intake manifold so it would warm up faster .
