LOOK AT ATTACHED PIC, CAN SOMEBODY TELL ME WHERE THE HOSES GO OR IF IM MISSING A CHECK VALVE.

YOU WILL BE LOOKING AT THE DRIVER FRONT SIDE OF THE UPPER INTAKE MANIFOLD.

THANKS,

It looks like you have an AT (Automatic Transmission) RX-7. Here is the good colored diagram, but it doesn't have the AT vacuum chamber. It looks like you are missing a check valve on the forest-green colored hose that goes to the vacuum chamber and the turbo control solenoid (mounted on the ACV).

Thanks for the replies

Hey Jonski,
Is it possible to elimante this check valve and just put the hose directly into the uim? Just a thought.

Thanks again!

No, you need a check valve. Otherwise your vacuum chamber would be pressurized under boost and no doubt cause problems with your secondary boost.

P.S. let me know if you need help doing your hose job...
**Hint** Use a small light hand torch (autozone) to heat the hoses before you try and slice/scrape them w/ a box cutter. O and don't do that on your fuel lines
