ProMeth Universal Tank Sight Tube

For those who want a simple, quick and easy way to see the fluid level in their tank without having to open the cap. We have our universal sight gauge kits. Installation is as simple as drilling two 5/8″ holes, inserting the two rubber grommets into the tank followed by two plastic barb fittings. Next slip the hose over the two exposed barbs and secure with two supplied hose clamps.
