My question is how reliable is the stock fpr with aftermarket fuel pumps. I'm running an external pump with my fuel cell.
If I do install an aftermarket one, probably aeromotive, do you just take the stock fpr off the fuel rail and cut out the internals or something, it's a unique setup with the fuel rail. So you almost need the fpr on there just to hook up the return to the tank. This post has been edited by czwalga: Feb 22, 2011 - 8:57 PM -------------------- -93 Rx7, Turbo 6.1L v8, 725rwhp/760rwtq

no you figure out the thread of the stock FPR and put in a AN fitting and run a -4 line to the FPR. then out the regulator back to the tank

I could be wrong; i'll have to take it apart tonight. -------------------- -93 Rx7, Turbo 6.1L v8, 725rwhp/760rwtq

Not a thread... like I thought. I really don't want to go through the trouble, I can't weld cast aluminum with accuracy, just tacks and stuff. I think i'm going to try and just use the stock regulator and see how that goes.
Welded on a bung.

Thanks.... that's pretty much the answer I was looking for. Wasn't sure if the higher volume pump would where the stock regulator out somehow. -------------------- -93 Rx7, Turbo 6.1L v8, 725rwhp/760rwtq
