Hey guys. I installed an adjustable frp last night. It has three taps for fuel. "In", "out" and "DRA". My question is, what is "DRA"? I know "in" is for supply, and "out" is for return. So "DRA" is suppose to be the pressure that's after it's adjusted, right? Or did I have it wrong? Is it suppose to be "DRA" for the return fuel line, and "out" is the adjusted pressure? I hope I am making sense. Please let me know, guys. Thanks.
