I'm not a Cat fan, it would be convenient because the Cat dealer is reasonably close. OPther than that, I can't think why I would change.
Originally, people started doing the cat swap because of the crappy stock fuel filter (only 10 micron, etc) but in the process a lot of folks ended up finding that messing with the fuel head at all tends to introduce small leaks that build up and fill the head with a big air bubble... I know. I had to rebuild it twice to get the leaks down to a tolerable level and smear the gasket with lithium grease, etc.
You have to pump/bleed the system at the head whenever you open it to the air (new filter/old filter, whatever)...unless you've added a lift pump near the tank.
If I could do it again, I'd just buy a RACOR head/filter instead of the CAT adapter. I like the CAT filters but the mopar head is still garbage. Regardless, the lift pump mod is a no-brainer if you have the aptitude to do it The only non-stock thing about it is that the part is from a dodge cummins. That's the next one on my list. With it, you don't ever have to pump the filter head again, the lift pump does it for you. You also don't have to worry about the vacuum being insufficient under high load since the lift pump is constantly supplying more than the injectors can use.
