It should be installed/spliced within the hose that leads to the innermost hard fuel line..the hard line closest to the middle of the car; that should be the sending line from the fuel pump to the engine and the one that will be getting the check valve.

I'm at a week now of driving it daily and still no hot start problems. It fires immediately no matter how long it's been sitting.

Me too, I am at 3 weeks and it fires quickly. I installed the $7 black plastic CV.
