Fuel Pump Removal
The fuel filter needs to be changed every 15-20,000 miles under extreme driving conditions.

Be sure to use either a LED work light or an explosion proof light. You don't want fuel to get on the bulb
and possibly cause it to shatter. You'd be riding in your B-Body in paradise before you realize it.
Procedure:
1. First, you need to raise the vehicle where the driver’s rear wheel is off the ground, the filter is located
under the body in front ofthat wheel.
2. To relieve the pressure from the system remove the gas cap. It’s best to unplug the fuel pump by the
wiring harness directly under the body below the tank fill tube while the car is running and let it stop. It
will take a second or two.
3. With the gas cap off, remove the bolts to the harness holding the filter in place.
4. Then use a set of pliers and a flathead screwdriver to unhook the hoses from each end. This is a little
tricky, but give a good look to them and you’ll see how they come off. Remember: There is still gas in the
lines and it will pour out, so have a pan handy and then keep it there until the gas runs out. It helps to tilt it
and remove the leftover gas in the filter.
5. Reinstall the new one in the reverse order making sure it is in the right direction and the hoses are secure
to the filter.
6. Reconnect the harness if you chose to disconnect it and crank the car. Turn the key to the “Run” position
and let the pump prime the lines before cranking.
Safety:
1. Safety First - Chock the front wheels or put
something in front to keep the car from rolling
forward.
2. Raise the rear of the vehicle a good amount. The
rear wheels of the Wagon should be at least 3" off
the ground. This should be just enough to use a
transmission jack and keep the tank mounted on it
and slide it out.
Procedure:
1. Loosen both hose clamps on the filler neck and the
one on the vent tube. When the tank mount end
comes loose, tighten back up the other end.
