ive been asking around about where to tap into the fuel for the nos. My domestic friends tell me i can tap in through the valve to check my fuel pressure, they called it the "shradder valve" or something i dunno how to spell it lol. its just a little knob they unscrew and hook up a fuel pressure guage to check the pressure, they said theve never seen an efi car w/o one yet so im guessing weve got one somewhere
It's basically a valve like you have to put air in your tires. I've seen them on many domestic cars, but there isn't one on our car. You can buy the test port from Toyota which is basically a double banjo fitting where the fuel line bolts to the rail. But I think it's fairly expensive.
