High volumn fuel pump question


New Member
I am changing over from a stock block to a stage motor (273 motor). I currently have stock lines with Reds Double pumper. Im changing over to a #8 (1/2" inside diameter) feed line and will use the exsisting feed line as the return and will use a Weldon 2025 pump. Question is the fuel regulator and inlet to fuel rail. I have the stock appearing- adjustable type and stock fuel rail. Will I need to change the regulator and modify the fuel rail? I see the inside diameter at the inlet to the regulator is only 3/8" and the inlet into the fuel rail is only 1/4"! Thanks for any input. Larry:confused:
