Default Vans gascolator

Hi all
I started to-remove the cowls with a view to inspect the engine bay
And thought it would be a good idea to clean out the gascolator
But it proved to much of a challenge for a novice like myself I twisted
And pulled the bowl but it did not move and I was a little worried about damaging it and thought if I do eventually get it off can I successfully reseal it so I have ordered a new I ring from vans just in case
Any advice from you guys would be appreciated

The gascolator provides a great seal against the "outside" air. As such, you need to activate the fuel drain on the bottom of the canister to allow air to enter as you remove the bowl. Otherwise you are fighting a vacuum that you are creating as you try to remove the bowl.

What he said. I have found it's still difficult to remove and I've found those rubber disks found in the kitchen to remove caps from containers to be useful to grip the gascolator body.

Make a "T" handle out of pipe fittings and screw it into the bottom port. That handle gives you something to grab hold of to pull down.

Same as Joe said. Remove the drain fitting, then use a short piece of pipe to wiggle the bowl down and out. Works great. Having a spare O ring gasket on hand is a great idea. I managed to butcher (pinch) one putting the bowl back on.

Try just running the fuel pump with screws removed and see if that helps!

I replaced the drain valve with one that locks open (please spare me the safety issue breast beating, I?m smart enough to check it closed after sampling). That eliminates the vacuum lock, but it?s still a bit of a chore to remove it.
