|Rebel13||I removed the valve completely, enlarged holes, made more holes and made another channel myself and will add a filter later when I am done working on my tank. You can still fill it all the way. The tank is suppose to breath in and out. They made it the way they did mainly in case you drop or lay down and fuel won't leak and lead to catastrophic accident. The problem is more then the valve, the holes are small, talking about 1/32" and then you got the alluminum corrosion sediment build up, doesn't take much to block.|

In theory, you can just sheitcan that rubber piece, but will never be able to fill up all the way. What i did with mine, was just to make the hole a lil larger (using a heated brad), and that kilt any issues.

|chiller||The pog problem is the vacuum diaphragm in the gas cap. If you remove the cap and take out the 2 screws holding the locking mechanism, the vacuum diaphragm is the first one you see and can be removed with needle nose pliers. If you're CAREFUL you can remove the diaphragm without ripping off the little tit that holds it in place. The diaphragm and mating surface is so smooth they tend to stick together, especially when it's hot out. I roughed up the plastic surface the diaphragm seals to with some sandpaper to prevent the two from sticking together. A little silicone grease to the diaphragm tit to help it go back in and no more vacuum lock and the tank will still keep the gas inside the tank if you spill. On a hot day the gas expands while sitting then wants to contract once you begin moving creating the vacuum on the tank. It doesn't take much to stop gas flow.|

It dissolved what ever was blocking the vent line, and I can easily blow air right up to the tank filler cap opening now, so the vent line is clear.
Guess I`m gonna have to take the cap off and finish the job properly by cleaning the cap vent to stop the whistling before I get stalled away from home.

|beeblebrox82||I can not for the life of me get the check valve out of the cap vent. I've destroyed the side of it pulling on it with a pliers. There's a ton of crap on the top of it. How the hell are you guys getting this thing out?? does it just slide out for everyone but me?!? @#%$!|

|Rebel13||It's the same at any level. With less fuel in the tank it is actually less noticable, air is compressable and liquid isn't. When you get a positive pressure, that is when your cap is leaking that you have mentioned. When it is negative it starves the carbs.|

|beeblebrox82||Question, have people experienced poogs with more than half a tank? My gas tank was nearly full.|
