High Flow Fuel Rail

Here's a cheap way to convert your stock later style fuel rail to high flow. It will help ensure a rich safe mixture by having plenty of fuel volume for big injectors, and it will flow just as well as aftermarket pieces, but for much less cost. It also may help richen up your mixture without doing anything else, almost like turning up fuel pressure.

After hacking off the tube at the end in the spot shown, and unscrewing the diaphragm. . .

. . . drill out the tube and pull it out from the side where the diaphragm was on. Then plug the end up where you drilled somehow. Or you could do what I did and take a piece of the barb you hacked off as shown. I got the little barb silver soldered on. I used the nipple to attach a little fuel pressure gauge to. I was also had a second fuel pressure regulator hooked up to it to reroute fuel through via a solenoid to up the pressure for high boost.

For the side the diapragm was on, I took an 18 mm (inside diameter) nut and had a piece of metal welded to it. I then drilled and tapped the piece of steel so a 1/8 brass fitting would screw into it. I then ran a long rubber fuel line from the supply tube off the fire wall to the new brass barb. You could make the end so you could run a braided line to it if you want.
