ULVER - IMO, Fleetguard are fantastic filters. I have been using them exclusivly for about 3 years. I even have experience with the LF-3554 which I am currently using in a 3.4L GM and my boat with the 4.3L as well.
Here are some spec's I got from Fleetguard a while back. Not sure what they all mean, but I liked the the fact that the LF-3554 has better filtration but still flows twice as much as the LF-782.
