Hey, that isolator will be fine. Fuel pressure at WOT will depend on static pressure and boost pressure. You want 1 psi of fuel for every 1 psi of boost. If your static fuel press is at 45psi and your running 20psi of boost......then you need 65 psi fuel pressure at WOT. With that stock hot-air your never going to run 30 psi boost so that isolator will be fine. If its rated at 80 psi, its fine.

Ill try and get that line this week if I can. Figure on about 50-60 bucks for 8ft.
