how do you install an a/f ratio gauge? what about fuel press.?

 

a/f: you should have 3 wires, one goes to one of the O2 sensor wires(usually white), one goes to power, one goes to ground

For the fuel pressure guage, you will have to drill & tap into the fuel rail. Hmmm have a look C at this http://store.summitracing.com/defaul...t=EAR%2D100192

 

you do not have to drill and tap the fuel rail to install a fuel pressue gauge, you just remove the Scharader valve on the main fuel line to the injectors and hook up the gauge here or if you have an aftermarket fuel pressure regulator, they have a pressure tap right on the regulator.

 

Oic, muh bahd! I've never put on on a stang. On my PGT the only way I found to do it was tap the rail then of course only after I tapped the rail I got a fpr I guess it was a good idea to buy a parts car.

P.s. nice new sig

 

try to be more careful next time! LOL bad advice can hurt someone if you're not careful!
and thanks for the sig comments. that's with my older 26x9 slicks, you oughta see the new 28x10.5 ones when I light them up!

 

actually a air/fuel gauge has 4 wires (not 3). one is the ground, one is the sending wire, one goes to your head lights switch (so it lights up when you turn your lights on) and the forth goes to the "key on" power wire (this way the guage goes on when the motor starts and turns off when the engine is shut off)
