Here it is! After many hours stamping, tweaking, welding and swearing, we have finally gotten it right! This is our new and improved SMOOTHER Instigator Gas Tank, made right here in our very own shop. So suck on that. These dicks hold about 2 gallons with the deep tunnel (shown) while the frisco-style holds 2.2. All tanks have a late style 74+ screw in gas cap bung, along with a female 3/8 NPT petcock bung. The tunnel has 1.75" of clearance. Tank measures 14" long, 9" wide and 7.5" tall.
