So the question is why is the pump on every other Mach sufficient? Or, is this just a sign that mine is near the end of it's life-span and should be replaced soon anyway?

Also, would another OEM stock replacement be good enough, or should I go with an higher-flow aftermarket?

As I recall, you've had a pretty much uphill battle with this car from the get-go. Happy for you that those days seem to be coming to an end finally.

They didn't leave much room for the early cobras and mach 1 guys as far as fuel goes. They use the same pump as the GT's with the terminator being the exception of course.
Yeah, you can see evidence of it in my AF chart as well. I'm comparing (overlaying in Photoshop) other dyno sheets from Mach's with the same cobra cams swapped in, and they are pretty much identical as mine up until around 4.5k, where mine takes a slight dip, then after 5k where my curve levels off and they all continue to climb up to around 320-325. I may run her on the dyno again after the pump replacement, hoping to get closer to the 320s.

Nearly, so far I've had to replace the engine, half the dash light bulbs, the rear upper control arms, re-weld and reinforce the rear upper torque boxes (one was completely off the car), have a crack in the chassis between said torque boxes welded, replace a brake line, fuel tank grommet, the front ball joints, and the steering rack. I'm really just trying to her into top shape to sell off at this point, so I can get a properly (or actually) maintained GT or maybe find a Mach 1 that needs some love.
