Default Fuel Filter Tricks?

Any tricks to getting the fuel filter off?

I have tried two different fuel disconnect tools and blistered up my hand trying to yank the lines off the filter.

Thanks.

The only tool you should need is a big screw driver or set of needle nose pliers. Pull the clips out of the lines (white tabs) and the lines will pull right off. You should have new clips with your filter.

Let me back up first... Which connections are on your filter? They started to change around 91-92...






Some other tips are to remove the pressure off the lines (removing FP relay while running), use a blow gun to remove debris if you have the spring lock connector, and push the line towrds the filter before pushing in the spring lock tool.

Penetrating oil, time, the proper tool, patience, more time, and a little bit of luck.

In that order.

Removing the pressure from the system via the shrader valve on the fuel rail is a good idea. It's also easier for me if I unbolt the filter clip from the frame.

I had to drop the gas tank to access the rear line. I then used the metal scissors type release tool. A BIG pita. Then I found the top of my gas tank was riddled with rust holes. Thank goodness for sheet metal screws and epoxy.

Definitely a pain. I spent another hour trying to get it disconnected last night. Still no luck.

Be careful not to damage the "O" rings in the fuel line. I made the mistake of "I'll change 'em while they're out", damaged one, then found out exact replacements aren't available. I wound up using an O-ring made of Viton in an assortment of O-rings from Dorman, which were less in thickness and smaller O.D. (I don't remember the P/N but it had 2 each 5/16" and 3/8" O-rings)
Good luck
