well i just pulled the tank on my buddy's renegade and the pre '09 fuel pumps are the same. they are just a lot more of a PITA to get out since you have to pull the whole tank.
i really think the reason why i've heard of more '09 fuel pumps failing is because of the larger in tank filter. the previous years have a filter that is half the size, so you'd notice the effects of a clogged filter much faster. when that happens, we all know to drop the tank and clean it. since the '09's have a larger filter, my theory is once junk gets past the pump and clogs up the regulator, the fuel pump gets overloaded and that is what actually burns it up. that also goes well with my theory that the '09 style doesn't have an inline filter because the regulator catches what the in tank filter misses. the '09 style goes from the pump, to the regulator, to the single fuel line to the injectors. the previous style went from the pump, to an inline filter, to a Y, to the injectors on one side and to the fuel return line on the other, which went to the fuel pressure regulator. the two line system works better for putting an aftermarket fuel pressure regulator in to jack up the fuel pressure. in the '09 style, you'd have to remove the intank pressure regulator and put one outside the tank. its not hard to do, but not as easy as previous years. these are just my theories, and i have been dinking for four hours (yes, i started at 10:15 AM), so take it for what its worth, lmao.
