Lowbrow Customs WX Gas Tanks were influenced by Harley-Davidson's WR factory race bike gas tanks. The beauty of the Lowbrow WX Gas Tanks are that with the included, innovative rear mount they will bolt right up to your stock Big Twin frame 1936 - 1984. Get a custom, narrowed look with a tight gap between the tanks, no fabrication required, these are the perfect tanks for a custom Shovelhead or Panhead. WX Gas Tanks have a capacity of 2.25 gallons and feature both a vent and fuel crossover and accept a 22mm petcock, and accept standard cam-style gas caps.
Tools Needed for this job.
3/8 drive ratchet
1/2 inch socket
Extend long flat head screwdriver
1/2 inch wrench
5/16 Allen or Allen Socket
Step 1 - Bolt the rear T-mount to your frame using 9/16 in wrench or socket. Shim between frame tabs with washers as necessary. Do NOT fully tighten yet. (Note: Make sure the T-mount back is pointed up not down)
Step 2 - Insert bolt through top front tab and into cast lug on frame backbone to hold one side of WX Tank in place.
Step 3 - Attach 1/4” inside diameter fuel line to crossover fitting on right tank, install hose clamp and fully tighten. Add an additional hose clamp loosely for the other fitting on the left tank. Push the fuel line into place on vent fitting of left tank when installing right tank. Put flat washer and nylock nut on top tank tab bolt and do not fully tighten.
Step 4 - Align the two rear tabs. The tab on the left tank should be behind of the right tank tab. Attach the WX Tanks with the supplied allen head bolt to the rear end of the T-mount using 5/16 allen wrench or socket.
Step 5 - The front lower tabs on the tanks attach to the stock frame tab on either side. Install and fully tighten the bolt and nylock nut. Fully tighten top through bolt and all bolts to rear T-mount.
Step 6 - Use a length of 1/4” inside diameter fuel line and two hose clamps to connect the fuel crossover fittings. Tighten clamps. Also tighten left tank hose clamp on the upper vent crossover line from Step 3.
Notes: Tanks are pressure tested at the factory, but it is highly recommended you or your painter pressure test it again before painting; it's cheap insurance!
