Changed my a few months ago and it was real easy. Get the tools used for
AC/Fuel connections (Package of about 5 plastic rings). Pick the one that fits
best 5/6" or 3/8" (Don't remember which) and push the rib on the plastic ring
towards the filter. The metal tubing will be slide off when you get it right.
The tubing just slides onto the new filter and clicks when connected. Remember
to take the pressure out of the line by disconnecting the fuel pump and running
the starter for a few seconds. There is a cut-off switch under the panel in
front of the passangers kick.
Remember to connect it back up before starting.
Hope this helps.
