Fuel Pressure question

I am having issues with my boost a pump constantly blowing fuses at WOT. I have an 06 vert with the A&A vortec S/C 6lbs boost and headers. Can I run without any boosting of my fuel pumps output? I do not take the car to the drag strip, only occasional WOT runs. What is the minimum fuel pressure my pressure gauge should be reading at WOT? Can I remove the boost a pump? Is it dangerous to run without it? Thanks for the help.

I definately wouldn't trust just the factory pump while under boost. There is a reason your BAP is blowing fuses. How is it connected into the factory wiring harness? Are the connections soldered, or wireless crimped connectors used? What size fuse are you running at the BAP and also at the factory fuse under the hood?

The Boost-A-Pump will blow fuses until the up to the 30A. I know several guys who have been stranded by this.

There have been no ill reported effects by uping the overloads to 30A.

Thanks for the input. Currently I have 20amp inline fuse but the problem is at the main fuse box. I am assuming I should run 30 amp at both locations.
