2005 Mustang GT Fuel Pump Fuse Blowing

Hello Everyone:

I am new to the forum :)

I have a Stock 2005 Mustang GT with 27K miles. Last week while driving the car stopped ( the battery/ alternator/inertia switch seemed ok) , basic testing indicated that the Fuse number 41 (fuel pump fuse blew).

I replaced the fuse with a new 20AMP and its working fine now. Originally it had a 15AMP. I have read all the other forms associated with Fuel Pump, Fuel Filter, Intertia Switch in order to figure out the root cause.

Realized it could be two main problems.

1. Fuel Filter gone bad ( which i dont suspect as the car is running with a high Amp fuse without any issues ( its been two days)
2. Shorting in the Fuel pump wiring / Relay.

Has any one had the same problem, Any suggestions why this would happen?
Does anyone have the fuel pump wiring diagram and possible places i should check for shorting.

Any guidance in this will be appreciated.

That's low mileage for an 05. The car could have been sitting for a while, and something gummed up inside the tank and hit the pump pickup. The filter should be replaced every 15k miles. Try that first. And please, please, put a 15amp fuse back in. It protects the related wiring. If it blows again take the pump out and see what's going on.
