Model Forum / Radio Controlled / Land Models / February 2004Fuel Leakage
Hi People, I notice on my Tamiya XBG, that when I open the throttle a little spray of fuel comes out of the top of the fuel tank. It _looks_ like it is coming out around the primer button. I can't see any way to seal it, so my questions are: 1. Is there any way to seal the tank properly? 2. Does anyone know of an aftermarket tank that will fit easily? Thanks Mike it might be there is to much nitro in it that might make it have to much presser http://community.webtv.net/METHODMAN03/traxxasstampede >1. Is there any way to seal the tank properly? Many people remove the priming pump from nitro tanks because of what you are experiencing...air leaks. If you want to keep the primer, you'll probably have to buy a new tank. I'm assuming it cannot be adequately repaired by the consumer. If you're willing to go without the primer: 1) cut the metal primer rod and remove it from the tank 2) thread a screw into the hole left behind...add some shoe goo or similar around the threads to ensure a good seal 3) allow the sealant (shoo goo, etc.) to fully cure before putting fuel in the tank. Later, Scott -- A: Yes Q: Is top-posting annoying? Hi Scott, I have no problem doing without the primer - I already order one of the Associated bulb primers which sits in line between the tank and carb. No now my task is to remove the existing primer. Are you saying I should get some decent set of snips or cutters and basically hack through the primer where is sits proud of the tank? Mike > >1.

Yep: * cut the spring * pull the metal rod up as far as possible * cut metal rod close to the tank * push the remaining piece into the tank (then remove it) Regarding the shoe-goo/sealant... the temp isn't the problem, it's the nitro fuel which might "eat" some silicones. Whatever sealant you use, you won't need to use a lot...just a small bead around the threads or the top of the screw. Later, Scott -- A: Yes Q: Is top-posting annoying? Thanks Scott, much appreciated!

Oh, one further question, what's shoe goo? Could I use some sort of silicon? Or would the exhaust gas temp in the tank be too much for silicon? Thanks MIKE > >1.
