PLASTIC TANK HAS A COUPLE CRACKS IN IT. ANYONE KNOW OF A FIX OR WHERE TO GET A NEW ONE.

You'll not likely find a new one, so a donor or proper repair will be your options. But repairing poly plastics are difficult because nothing sticks - at least for any length of time.

I have used this on door panels, plastic dirt bike fenders, urethanes, etc. It is simply amazing and works as advertised: http://www.urethanesupply.com/Airless-Welders-1/Micro-Weld-80/

I weld them using a soldering iron

Do a google search for plastic fuel tank repair. A body shop in your neighborhood may be able to weld it for you.

thank you i have a direction now.

I use the same plastic as the tank is made from to weld with
