SVT Focus, Cobra, GT500 pumps will not work in a return style fuel system, at least not for long. They are designed to adjust fuel pressure constantly through varying the voltage (the ecu does this). You need fuel pumps designed for 86-97 car's. Your standard Walbro 255 is suficient to feed a stock Cobra engine. Combined with a boost a pump, you'll have enough fuel for up to 600 rwhp.2. If you decide to go with the fuel mod's you have listed... You're looking at over 1k in fuel.3. You don't need braided lines, if you go with a return style, you merely need to add return style rails, build your crossover piece, and add an adjustable FPR. Hook it to the stock lines and the tuner will handle the rest.I made 500 rwhp with a 255 walbro, ONLY. I really needed to go to 60 lb injectors and a boost a pump to get the most out of it, but I never did. I just tried to live with the fact that my DD car made more power than 99.9% of car's running around on the street anyway, managed to pick the pieces up and move on.Cobra's don't run into fuel problems with their stock systems until around 500 rwhp either...Again, I say keep it simple, get it running, and deal with upgrading the fuel when you upgrade the blower, later down the road. There's no need to get all kinky and throw that kind of money at it yet.</blockquote>
