This Wassell Peanut Mid-Tunnel Gas Tank features heavy gauge steel construction, two 1/4" NPT bung, and undrilled DIY mounting tabs for custom installation. This mid-tunnel tank has a tunnel that runs about midway through the gas tank, keeping the gas tank down lower on the backbone than a Frisco mount version, which sits up high on your frame. It holds approximately 2.1 gallons of Go juice (that's gasoline, big fella), and accepts any cam-style for unparalleled chopper authenticity. Note: It is highly recommended to fit your gas tank to your bike before painting. Check for clearance or mounting issues as different combinations of triple trees, risers, and handlebars may cause clearance issues when turning. Tanks are pressure tested but it is highly recommended that you or your painter pressure test it again before painting; it's cheap insurance!
