Okay VERY dumb question but does anyone know EXACTLY what wrenches needed to get the fuel filter out of a 1984 2.8 carb'd Firebird? I have tried metric and standard wrenches and they ALL slip on the furthest back nut behind the carb.

Help?

 

Have you been using a line wrench or just a regular wrench? A line wrench works best.

 

Okay I have NO idea what a line wrench is, all I have are normal craftsman combo wrenches.

 

Jurel- I found a picture. These wrenches are made for flare nut tubing connectors. They grip on more sides of the nut than a standard open end wrench. If the flats on the nut are rolled over it might be tough to slide the flare wrench on it. Make sure you hold the other fitting (on the carb) with a wrench also. Previous owner of my car didn't use flare wrench and the nut is wasted- I need to use vise grips to remove it and I'll replace the pump to carb line.

 

Okay now that I know which tool I need, any one know which size? At 15$ a pop I can only afford one right now, not a half dozen :/

 

You could also try a LARGE open-ended adjustable wrench. I've found that to be more useful then the flare-nut wrenches on brake lines. I think it has to do with the thickness of the jaws on a large adjustable wrench as opposed to the jaw thickness of the flare nut wrench. Plus the larger wrench allows you more leverage without the possibilty of side-loading the tool (and stripping the nut).

Make sure you use the adjustable wrench the correct way. You might laugh... how can it be used improperly? Well the fixed jaw should hold the "brunt" of your force. Don't rely on the little adjustable jaw to do anything other then hold the wrench tight on the nut. Let me edit a picture from craftsman's website...

Okay, here we go. This should explain what I'm talking about. The picture is the head of a Craftsman 18" adjustable wrench.
