Here's a NEW plastic replacement gas tank for the 1986-87 TRX70 fourwheeler.  It comes complete including the gas cap and dual fuel flange with o-rings. Replace that rusted, leaky tank today. No more worries about interior rust or dents and dings. PLEASE NOTE: When using the factory fenders with this tank you will need to enlarge the opening on your front fender about 1/8" to allow enough clearance for the neck on the replacement tank to pass through.
