Has anyone tried to connect the inlet side of the fuel rail to the end side of the rail right before the regulator?

Almost.Like a dual feed? I'm not visioning what you are asking.
True. My hypothesis is: The fuel pressure may drop slightly at the last cylinder. Connecting the inlet side of the rail to the end via a small 4AN should reduce pressure drop at #1. I understand that a liquid is incompressible and that delivery volume is not a concern if fuel pressure is constant. It still does not explain #1 going lean on much higher HP applications than I will ever run. You think there is any merit to this?If im understanding everything correctly you would not want to change the feed to the regulator side because you dont want the regulator bypassing fuel to maintain pressure before it reaches all the injectors.
The fpr is what's referred to as a "snap valve" wich can only be truly closed up to xx% of set pressure. A modulating valve would actually work better, and decrease pulsation. My thought is that the extra feed (volume) after injector pulses would at least help. Maybe not.I think this boils down to the pressure vs volume argument....the injectors need a constant supply of volume at the proper pressure to achieve the desired results...if you try what you are suggesting the pressure in the rail may remain the same but you would be shooting yourself in the foot taking away the volume of fuel running through the rail because the regulator would be bypassing the fuel flow before it can reach ANY of the injectors....it would just be moving the fuel delivery problem around and not really solving anything.
Actually, i think . . . It's the opposite. Fronts run rich given same pressure/vol of the fuel system. Rear cyl get more air, and pp redirects to balance air flow.lean cyls power plate it lol
Thanks for sharing.I did it on my old Stage ll motor several years ago. It worked fine on it. But it was after market rails.
