When I turn the ignition on, without starting, the fuel pump is loud as hell. I don't remember it being so loud. Normal or should I have it checked out?
Amen. The 12v mod can also cause other problems like going lean after the car has been on for a while as the fuel pump can overheat running 12v for extended periods.Steve Jarvis said:The 12v mods is not needed unless your using the FFCD. If you are using a Greddy BCC, you should not do the 12 volt mod.

Do you know this for sure? Never heard of this, as 99% of in-tank fuel pumps on any given car run 12V (actually 14.4V) all the time. It sits submerged in gasoline, I don't see how it can overheat unless you were real low on gas.Andi said:Amen.

I experienced this problem myself... going lean at WOT during long trips....AnArKey said:

LowerJerZey: Yes it will be louder. Stock it doesn't run until the engine starts. Now you actually hear it run. Do you notice it when the car is running? You shouldn't, so it's no big deal.
Now a external pump, THOSE are noisy.
I did the mod because I plan to be BPU++++ by spring. I was taking out my spare the other day so I just did the 12v mod to get it out of the way. Just to be safe I'm gonna undo it. But, should I redo it once I'm BPU++++ or is it unnecessary. I am running the Greddy BCC.Steve Jarvis said:The 12v mods is not needed unless your using the FFCD.

It's unnecessary. The only time you would need to do this mod is if you do the FFCD which is in itself not recommended.LowerJerZey said:

Bryce disagreed, Jarrett agreed. Jarrett in fact is the person who told me to undo the 12v mod for this reason.Grant said:Andi, if I remember Bryce disagreed with you on the fuel pump overheating thing. I've also seen 16V to the pump on one car with a GReddy A/F gauge and he says hes never had a problem.
Its great if you want to do 12v, TTC and EGR, saves $100 for the BCC.
