If you have any fiberglass resin and chopped strand cloth, 1st verify that the resin & hardner mixture won't "eat up" the plastic. Do a small test patch on the plastic--or maybe there's another component on your machine made from the same plastic? If the resin cures without damaging the plastic, then you can take a 12" (more or less depending on the size of the tank's neck) square piece of chopped strand cloth and tear away small pieces of the cloth and apply around the neck. The cloth I use come in two layers like paper towels. Split the section into the two layers and it's alot easier to work around corners, etc. Again--all this is useless if the plastic reacts (softens up) to the resin-hardner mixture and the curing process. If the resin works OK with the plastic, then apply three to four separate "coats" of resin+cloth around the neck and in way of the crack. Let the 1st layer cure and then do a little rough sanding (40 grit) and then apply the 2nd layer of cloth/resin. Subsequent layers can be applied within a couple hours of the previous, depending on temperature and how hot you mix the batch. (Don't mix too hot though since you're working with plastic.) Forgot to mention also to degrease the area and rough sand (40-80 grit) and thoroughly dry the surface prior to applying the resin and the cloth layers.
