Default Single Plane fuel line set ups?

Pretty sure I asked this before but how did you guys set up your single plane fuel lines?

Im thinking loop the front rail's put the FPR on the back return side and one on the pump side? This sound right? I know some of you have done it different with y-blocks etc Why is that better vs what Im thinking?

Pics would be great!!!!

Ok I decided Im going to run a y with the feeds going to the back of the rails and the regulator on one of the front rails looped to the other rail, then the return of the reg.
Since I have the Speedinc fuel line relo kit already it should be pretty simple. Hardest part is decided where to mount the y-block. Should be very close to OutlawZs set up.

Parallel feed it, dual lines in, dual out then merge them. Your regulator should be after the rails not on it. You can get pressure influx at injectors if it's right on the rail.

Never heard that before. How far off the rail does it need to be? Looking at Jason OutlawZs pics his is exactly what I was going to do, his is right on the rail. He has a pic up in my LTX motivation thread if your curious to how he did it.

parallel feed to the front of the rails, straight out the back with 90° fittings into the regulator mounted on firewall. Return line goes out the bottom.

This is how I will be running mine. Makes for a much cleaner install IMO.

Regulator must be at least 6 inches from firewall.

Not the way I would do it. The regulator hanging off the end of the rail looks like it could break off causing a major fuel leak. Stuff gets bounced around alot when you are accelarating at high speeds .

Just ordered all the stuff to run a parallel set up and some new rails since one of them from clint was fucked up. Now I just need to see how you guys mounted it all.
