Okay, who has changed the fuel filter. Does it take a crow bar, or just a
big hammer?
big hammer?
so if its in the tank how do you change it? pull the sending unit?rob92xj said:The CRD fuel filter is next to the brake booster. Gas KJ it's in the tank.
Is it necessary to loosen the relief valve to pump air out of the cannister? I believe that is what I did when I drained the filter once checking for water.rob92xj said:Should need just a few wrenches, don't for get to prime the fuel system after replacing the filter and DO NOT pre fill the filter install it empty, pump the primer about 10x and try to start it if it does not start in ten seconds, pump the primer another 10x. Cranking the engine over 10 seconds willl damage the CP3 high pressure pump, it's a good pump just not tolerent of no fuel volume due to the very close tolerences in it.
Thanks Rob,rob92xj said:The bleeder valve next to the filter is for draining the water out of the water seperator, lossen the bleeder then open the drain valve.
Have the bleeder closed when you are priming the fuel system with the hand pump mounted to the filter housing.
I was told by the Jeep dealer that it's a lifetime filter, and that it doesn't have to be replaced until the time comes to also change the injector pump. They said that today's gasolines are refined well enough so that changing filters every 6,000 miles isn't necessary. At least that's what they said. I use a bottle of STP fuel injector cleaner in my gas tank every 3000 just to make sure everythings kosher.m90daytona said:off topic, can you change the fuel filter in the 3.7 liberty if its in the tank?
gassers have two fuel filter, 1 is in tank, 2 is right next to it, access from inside the cab/trunk per chilton book manual...:rtft:rob92xj said:The CRD fuel filter is next to the brake booster. Gas KJ it's in the tank.
The one on the fuel pump is likely the most frequently changed. Unfortunately, the one in the tank is probably the most needed to be changed (if ever) because it is the first line of defense.lucas/liberty said:gassers have two fuel filter, 1 is in tank, 2 is right next to it, access from inside the cab/trunk per chilton book manual...:rtft:
There is only one filter on the 2.4L/3.7L KJ's and its in the tank...get a real service manual with the correct info.lucas/liberty said:gassers have two fuel filter, 1 is in tank, 2 is right next to it, access from inside the cab/trunk per chilton book manual...:rtft:
