If you use the intank pump be aware that if you use a return style regulator you will have pressure problems. The return line is too small to flow enough fuel to keep the pressure in the 7lb ballpark. I removed the injection on my 88GT and went with a carb. With the return type regulator the best I could do was about 15lbs until I replaced the return line. The factory line is what helps with fuel pressure needed for injection. Have any questions pm me.
