I purchased and installed this kit as a cheaper alternative to the FASS system at $700.00 plus. So far so good. I have only driven a few hundred miles. No problems yet. I have installed 2 different pumps and all others leaked externally or shorted out. This one is on an 03 LB7. I love the fact that psi can be adjusted with a flat head screwdriver and it comes with a spare screen and orings if needed. Mine is adjusted to 8psi at idle and runs great. Pump is a little noisy hence the 4 star rating. Otherwise, a good choice so far. Will see. Other brands failed between 1000-3000 miles and yes they were wired up correctly with no ground issues and no fuel contamination issues.
