Pretty easy mod to do. Use -4AN pushlok hose to clamp onto the barbed rail ends after removing the factory hosing. At either the front or rear of the rails go to a "Y" with both -4AN hoses and out with a -6AN. Take this all the way back to the tank, drop the tank and clamp to the factory outlet.
Here is an older photo where you can see the -6 going to the Y and the two -4 lines going to the rails. There are barbs at the rails the -4 lines are simply clamed to. I used the FI type hose clamps, better than worm drive style. The other end of the rails can be used also, but NHRA rules require that lines not cross over the flywheel area so I ran this setup to the front. The stock feed is capped and I am using the stock return as normal, the regulator functions the same.
