So, quick info on the setup. Mildly built 306, Vortech V3 10/11psi, Aeromotive 340lph in tank pump, used 42lb injectors, Kirban FPR about 12 years old. Stock fuel lines, stock fuel rails. Car dynoed 480/470 at the wheels.
Took the car to the track last night, and started getting some missing in the higher rpms (I would guess above 4000). On my second pass I watched my fuel pressure and watched it go up as the car started to build boost, but it quickly started to drop once I got in the higher rpms. Not wanting to grenade my engine, I called it a night. I do NOT have an air/fuel ratio gauge, but it IS on my list now. On the dyno the car kept a good A/F ratio. Gas tank was also completely full last night.
Does this sound like the stock lines are falling short? I've heard of people having no problems with stock lines and rails at my power level, should I roll the dice and try a new FPR? My current one does have some age on it, not a lot of miles though.
Right now I'm leaning towards a complete fuel system, just not sure which route I want to take.
Option 1: Pro-M hanger keeping the single 340lph and with -6 PTFE fuel lines with Glenns or Behind Bars Racecars rails. I feel like this would be the cheapest option and would be perfect for my power level, however no room for growth and probably not enough for E85 if I wanted to give that a go.
Option 2: Glenns Performance 03/04 Cobra tank setup. Can't really afford this setup right now ($2000+), but seems to be put together really well. Pump hanger has -8 going in and out which I like, also has the ability to run multiple in tank pumps for big power. No fuel filler mods, stock fox one is suppose to work.
Option 3: On3Performance kit. Cheaper than Glenns, but you get what you pay for. Hanger has -10 going out, -8 coming back. Again, multiple in tank pumps an option. Have to buy a newer style fuel filler and have it modified. One plus is this place is 1/2 hour away, so I could go and pay cash and avoid shipping.

Question: I feel like a single 340 pump is enough for my power level, but can it push enough fuel through a big line like a -10 by itself? I don't want to overbuild it with two big pumps just to have the fuel circulating around and getting hot.
Sorry for the long post, just trying to get some input and provide plenty of info and what I'm thinking. Thanks guys.
