Just picked up a fuelab 51502 fpr and have a quick question. I am usjng the 3000gt rail with the crossover pipe meaning fuel will be fed to both rails via a feed port for one then loop around to the other rail and out. The fpr has 2 feed ports and a return port. I am wanting to clarify my assumption in hose routing. If I run feed from pump straight to rail one, fuel loops to rail 2, a hose from rail to to a feed port of the regulator, and a hose from the regulator return port to the factory return line, will the regulator work properly?

You'll need to plug one of the inlet ports on the fpr that's all

That's what I was thinking. Later down the road I plan to run feed through a distribution block once I get the upper coolant neck clearance resolved. Then each rail will have dedicated feed and return. At this point, I just want the car running.

This is the simple option for a FPR on those rails, that my brother used on his. granted he's running a plenum spacer, and shaved a little off the plenum to accommodate the adjustment threaded section.

I considered the honda to fpr adapter. I have worked with 3sx for a few years now since owning a 3000gt.

with your setup, I would do it like I did ZcarGo's with a loop in the rear between the two lines, feed on the passenger side, and outlet going forward to the upper support, where I had the Aeromotive FPR located. blocked one side, had a 90 into the other side, and a 45 degree out of the bottom running back to the return pipe at the rail. I also used 5/16 pipe to -6AN fittings, for -6AN the whole way!

I mounted the FPR on the firewall directly beside the vin impression. ran a line from filter to passenger side rail, loops around front of manifold to driver rail to then it flows to the regulator and the return line comes out of the bottom port straight to hardline
