Replacement Fuel Pump

The factory pump in my TTA finally gave up. I was wondering what other owners were using for replacements. My car is pretty much stock. Aftermarket exhaust and K&N filter. Runs high 7s in the eighth. I have no intention of doing any more mods on the car.
 
i'm gonna use a deatscworks pump on mine, haven't bought it yet though check with arizona gn nick male
 
Just ordered deatchwerks dw300 from Nick Micale an hour ago! It's a quite pump made in USA but beware, it flows. I fully expect it to overpower the return line and as a result, not be able to turn my FP down. I'm going to be running E85 so the higher base FP won't be a problem.
 
An Aeromotive 340 is more than enough for mildly modified cars using gasoline. It can provide 600+ hp of volume and unlike a Walbro 255 lph, deliver 70 psi of pressure while doing it. So you can safely use up to (70-43 =) 27 psi of turbocharger boost at that horsepower level. No special fuel pressure regulator required.
 
At full rated output, 255s only produce 60 psi. So that means that above (60-43=17) 17 psi of boost (which is stock for a TTA), you'll be leaning out some or else have a really goofy injector fuel calibration that will slop fuel in there instead of metering it carefully like a well engineered car. No need to take chances. My advice is to get the Racetronix fuel pump upgrade harness to get lots of volts back there, but use an Aeromotive 340 pump for a nice safety cushion. The question was about a mildly modified gasoline fueled car, so although a Walbro 255LPH, Aeromotive 340 and dw300 can all handle E85, that capability is moot.
 
Do you have the Aeromotive part number? I looked on the home page and couldn't find an application chart. The Aero 340 sounds like the pump I need.
 
Ok I figured it out. They don't show a Trans Am with a 3.8 but they do show a 5.7. Also they show a Buick Grand National. Both take a part #11169.
That should do it. Thank for all the inputs
