I know what it does. I guess the technical term would be a one-way check valve or a pulsation dampener. It keeps the fuel rail pressurized when you turn the key on and the pump primes for a second then shuts off. This little thing keeps the pressure from backing off while the pump isn't flowing, or between pulses of the fuel pump.

I just don't know what the damn thing is called and it's gone bad on my turbo LS. It's causing tuning problems * I think*. When I get on the throttle hard that check valve isn't holding the pressure steady on the rail, so Ii'm getting varying A/F readings from my wideband. Granted it's not a large fluctuation, but varies the A/F ratio about .3~.4....

Does anyone know where I can get one?

Thanks for any help guys.
