For those of you into vintage rides, youll remember the Sight Gauges installed on the outside of old oil & gas tanks. There was this clear tube that ran up & down, and you could see the fluid level...those old rides sure leaked oil, so you had to know when to add more! Well, we think that was a way cool accessory, and our buddy Kirk at Custom Design Studio has put together a kit with all the parts you need to install one on your retro build as well. The kit includes 2 weld-in 1/8" NPT bungs, 2 ninety degree X 1/4" X 1/8" NPT fittings and an 8" length of transparent, fuel resistant urethane tubing. (Cut to length and use hose clamps of your choice to secure). For use in custom show bike applications only, with welding of bungs into Gas/Oil tank required. Made in USA by Custom Design Studio.
