Fuel pump/pressure related...

Anyone know what the stock fuel pressure is?
Also, what are the specs on the stock fuel pump (LPH, max HP supported)?

If say the stock fuel pump supplied (just for arguments sake, not nearly actual) 10 LPH and I bought an aftermarket one that supplies 30 LPH and the pressure was higher, keeping the rest of the fuel system stock, what would this hurt or anything?

with the key on and not running the pressure is between 41-47 pounds.if you put a bigger pump on it will have no negative affects.the regulator will keep the pressure where it belongs
