How difficult is it to change a gas filter on a c4?1995

 

Depends on the year, my car takes just a few mins. It's very simple and easy.

 

It's not hard, but it's a messy job. If I had it to do over again, I'd probably let someone else do it - not terribly expensive.

Best to do it when your tank is low on gas. You need to relieve the fuel pressure - some folks have luck pulling the fuel pump fuse, and running the car until it dies, but that didn't work for me. Remove the gas cap and relieve the pressure on the schrader valve. Then you need to loosen the fuel lines at the bracket in the engine compartment and near the fuel filter. Use line wrenches to loosen the filter, and be prepared to catch fuel that spills from the lines.

 

It's not real fun. It's located inside of the front frame on the passenger side. Cat is in the way somewhat. Try to find a plug to cap the gas line and have a container with a rag in it (to prevent splashing) ready.
Wear eye protection before loosening the lines as you will be on your back looking up.

 

Call me an Old Softie, but???? Remove the filler neck rubber boot and pinch off the fuel lines, or disconnect them. The fuel from the tank will siphon once you disconnect the fuel filter. Do it in an open area or turn off your water heater before you start, keep a fire extinguisher handy. If you have to use a light make sure it has a plastic cover to protect it from breakage during the replacement. The filter removal is in a tight spot and will take a little patience. It's hard to have patience when ther is gas spilling down your arm, and on your garage floor. Make sure you have the proper "O" rings (GM, not from Autozone) Relieve the pressure, get the tool to disconnect the fuel lines at the fuel rail, undue the filter mounting bolt, undue the inlet side of the filter, remove the entire assembly. Replace filter, new "O" rings and reinstall. You should use flare nut wrenches on the fuel line and filter, back them up or you may twist the fuel supply line (you don't want to do that)Don't fool around with gas in an enclosed space with an ignition source. I've heard of a few fire accidents burning down houses and cars. Take your time and be safe. Any questions come back here and ask again, and again.
