Rep Power: 282 If you mean you have a mechanical gauge, i.e. tube running into it, not only wires, I hope you have an isolator. It is dangerous to run pressurized fuel into the vehicle, if the line breaks, you have the potential for disaster.
Basically, you will have to tee off before the fuel rail. It is the long silver thing that is on top of the injectors, the line should be on the left side.

First find the fuel line
Then buy a metal fuel T , a small fuel line hose for fuel injection about 3" and clamps from any auto shop
You'l need 3 clamps
Cut and by pass your fuel line. (there may be some fuel under pressure have a rag ready)
Your sensor sholud have an fuel line input, connect the line into it.
Look for an opening in your firewall then run the wires into your cabin through the fire wall.
then connect the red wire to positve then black to ground and the remaining wire should be the signal from your sensor.
Your gauge should have instructions included.
Test for leaks by inserting your key and turning it in the switch position
(don't start your car)
while the key on the switch possition check the line for leaks
I no leaks are detected you should be reading presuure on the gauge.
If is leaking take the key off the switch and secure your connections.
