I replaced my fuel filter several months ago on a 99 Plymouth Voyager with 4 cylinder engine. This van has 200,000 miles on it. This was a pre-emptive replacement done as preventive maintenance; the van was not suffering from a bad filter at the time.
When I changed the filter I was surprised to find quick-connect fittings on the tank and the line going toward the engine, but the fittings worked OK and all has been well for several months. 2 days ago my wife was driving the van and it died in a parking lot. When I looked at it, I found that the quick connect fitting had come apart where the filter attaches to the pump nipple on the tank. I assume that it blew off because of the high pressure. I snapped it back on and everything worked well again, although I want to make sure it doesn't happen again. My wife drove the van again last night, and the other line blew off, the one going toward the engine. Once again, I snapped it back on and we drove the van home.
What I need to know now is if this is a common problem with this vehicle, or if there is something else wrong. It can't be a dirty filter causing excessive pressure, because for one thing I put in a new filter, and also both lines blew off on both sides of the filter, which wouldn't happen if the fuel could'nt pass through the filter. Could it be that there is something else obstructed in the path to the injectors, downstream of the filter? Has anybody else had this problem? Or perhaps my problem comes from the fact that I used a cheap aftermarket filter from Autozone. Does my filter simply have crummy connectors on it? All of the manufacturers use plastic connectors. What do you guys think?
