Running enduros this year and want to open up the filler neck. I saw some suggestions on the old forum, but they all related to older cars. Is it any different on a 99? Any tips?

Use a dremel tool with a small cut off wheel. Cut the insert all the way around, then pull the rest out with long pliers.

Remove the filler neck from the car first. We use a holesaw to remove the restrictor, then clean it up with a die grinder.
While you are there, make sure the plastic flapper at nthe bottom of the filler neck is moving freely, they have a tendancy to stick.
Clean well before reinstalling

Thanks guys.

How'd I do?




For the next guy: used a 1 1/2 hole saw. Saw fits nice enough that I didn't even need a vice to hold the pipe. Then used a screw driver and pliers to pull the little flap out. Dremmel to smooth out the edges. Washed it out good with water, including the vent tubes.

+1. Opening up a fuel filler neck is really a bit hard on any cars. I read about a simple mod to 'open' up the fuel filler neck to allow the use of the big rig hi flow nozzles. My 2000 has a reduced inner hole with a spring loaded trap door. This piece is made of some sort of nylon and is pressed inside the fill neck. To keep plastic shards from falling in the gas tank, I removed the fill neck from the tank. It took a little work after loosening two hose clamps from the fill hose and vent hose. Once the clamps were loose, I had to twist the filler tube about 180 degrees counter clockwise to get enough room to get it from under the fender.

As a side benefit, removing the neck from the car prior to cutting prevents rapid combustion.

This worked like a charm! Tks for the tip.
