why dont u just take a drive....

 

or just wait a week or two...no need to waste money. have patience, its not like the fuel pump is going to give you a jolt of hp that you just cant wait for.

 

yeah, be patient and be safe when doing it. It's not going to give you instant hp after installing the pump. The pump is only there as a safety mod, plus make sure you get it tuned after because you're going to run rich.

 

I have done it with a full tank and an empty tank.....just a little more messy with a full.

 

i tried but you end up letting about a gallon run onto the ground, and your car smells like gas for 2 weeks.
