fuel pressure question?


I have a procharged 02 gt and i have done the 2003 cobra pumps and tank swap. i have noticed that the fuel pressure drops to about 10psi around 5200rpms and it really seems slugish. Is that enough fuel pressure? i dont know if it has any thing to do with it but Also my check engen lights on i will have the dts codes posted tomorrow?

umm no - you should stop driving... i think its supposed to be like 25-40

did you get more voltage to your pump by swaping connectors and such

now what do you mean more voltage? all i thought you had to do was change to a 03 cobra tank and pumps and nothing else.

thanks for the help guys. and i will have the dts codes posted tommorow.
