2.1 Gallon Narrow Sportster Style Gas Tank with "Frisco Style" low tunnel to let the tank sit high on the backbone. For years, people have been modifying OEM Harley Davidson Peanut Sportster tanks by cutting them in half, narrowing the tank by removing a section of the middle, and welding everything back together. This look is great, but accomplishing this modification on an OEM tank is very labor-intensive. Fear not, for we have your solution at a great price! This tank is 100% brand new construction and has the same shape that is achieved when you modify/narrow an OEM Harley Sportster tank, but without all the work!
The cap bung is set up high (for max fuel capacity) and is a standard OEM Harley cam lock. You can find a chrome gas cap here and a black gas cap here. The 1/4" NPT petcock bung has been placed on the side near the rear of the tank for maximum fuel usage as well. This tank is the highest quality TIG-welded construction and is pressure tested at the factory before shipping. Please see the photos for dimensions.
Even though these tanks are pressure tested from the factory. We recommend sealing any custom tank with Tank Sealer before painting. Use the Universal Mounting Kit for easy install

Prism Supply Co Petcock 1/4" NPT
Regular price $145.00The Prism Supply Co petcocks are guaranteed for life! If you're having an issue with it you can send it back to them and they will rebuild it for no additional cost!
This unique petcock fits direct to either a 1/4" NPT bung on your gas tank. This keeps your gas tank looking very clean. It features a 5/16" diameter hose barb on one end and a fuel filter on the other. We recommend using our 1/4" Fuel Line for a snug, leak-proof fit. Rotating the cylindrical piece with the two grooves is how the fuel is toggled on and off. The fuel line does not rotate while toggling the fuel on/off. No reserve.
Many custom and aftermarket gas tanks use a 1/4 inch NPT or 3/8 NPT petcock. NPT stands for National Pipe Thread and it is a tapered thread that seals as you tighten the petcock into the threaded fitting on your gas tank. Lowbrow Customs makes petcock adapter nuts in both brass and chrome that allow you to adapt your 22mm petcock bung to accept either a 1/4 inch NPT or 3/8 inch NPT petcock.
