essential..u will cut the brake booster line in half...after the clip..and few inches cut it...then you will insert one of these metal pieces like below to reconnect the brake booster hose u just cut and it supply a nipple for your FPR

i have no idea where to obtain this fitting...

I wouldn't do that...it also refs vac. Tap a fmpr before the throttle body. That way you can set the base pressure at 58psi and it will only ramp up 1:1 with boost.

actually if you used a check valve than it would work....but ive never heard of fuel pressure dropping because vacuum was going to the FPR.i didnt think that was possible

One way check would work great. Some Front Mount Fuel Pressure Regulators do reduce fuel pressure based on vac...just like they ramp up fuel pressure based on pressure.

I tapped my inlet pipe before the throttle body and took that reference to the regulator.

This will get ya close. You see where the line leaves the Wedon regulator and travels between the fender and the abs block. Then it leaves the pic and turns into the black pipe that has a barbed nipple....so boost only reference.
