Just a quick check before I install.....

The check valve that is directly behind/below the crossover tube from the y-pipe.... and just under the front of the little black plastic box above the engine......

which way should I install the new check valve so air flows right to left or left to right ???

thanks....

You want the check valve between the y-pipe and pressure chamber to point toward the pressure chamber.
