not hard you just cut the fuel line and put in between then get power for it, I got power from the fuel pump rewire mod relay. haha just doing the rewire makes you pump louder. It's like a buzzing/vibrating sound. At night you can hear it really loud, but after your driving around you don't seem to notice anymore or you could just turn up the beats.

The Airtex inline pump kinda just hangs on the ebrake line, haha looks a little unprofessional but its been working for quite some time. That sucka pumps too!
