The tanks that come with the Losi LST / LST-2 / Aftershock / Baja STINK! They're very prone to air leaks through the primer setup so its a good idea to remove the primer and its come up a few times recently here and I happen to have a few tanks I was doing the other night so I thought I'd take some pics of how to do it:
Step 0 - Curse Losi for the bad design!
Step 1 - Using your hands or pliers pull the black primer knob off of the tank
Step 2 - Using a small machinists pick or the like pull the primer post out of the fuel outlet at the bottom of the tank
Step 3 - Next push the portion of the post that is still sticking out where it was attached to the knob all the way into the tank, again a small pick is useful but you can use a hex driver or anything small enough to get it done
Step 4 - Using small needle nose pliers remove the post from the tank as well as the washer and o-ring from the top of the tank
Step 5 - Last is to seal the hole in top of the tank where the primer was. The most common thing to use is JB Weld, I'm trying out a new 1 minute epoxy to see how it does. The only problem I ran into with this epoxy was that it was a bit thin and wanted to drip into the tank which the jb doesn't do.
And here is your new primer -less tank: (the only reason I removed the filler cap is I was dying this tank, its not necessary for removing the primer
