I think it will be worth it in the long run.

The stock fuel rail on my car has a smaller line atached to the top of it. I figured this was the return line for my system. The BDL rail that I have does not have this, nor does it have an aditional hole besides the supply and mounting holes for the reulator. Does anyone know of a good fuel pressure regulator that has any return capabilities?

I've been looking, but wanted to ask before I spent the money on one.

In addition I have been looking into purchasing the Greddy E-Manage , any thoughts on this piggy back system?
