SIMPLE MECHANICAL FUEL LEVEL READING NO POWER NO HASSLE
Mechanical dipstick gauge for bulk fuel tanks. DN40 (1.5 inch) BSP male thread, 350mm probe length. Direct reading, no power required.
Direct visual check
Dipstick design gives you an instant fuel level reading. No batteries, no wiring, no electronic sender to fail. Screw it into your tank top, pull the indicator, read the scale. Job done. Suits workshop tanks, site bowsers, and any diesel storage where you want a straightforward visual check without faffing around with gauges that need calibration or power.
Standard BSP fitting
DN40 (1.5 inch) BSP male thread fits most Australian tank top fittings. 350mm probe length suits tanks up to that depth. If you're running a shallow tank or need longer reach, confirm depth before ordering. Installation is straightforward: thread seal tape, hand-tighten, done. No special tools, no adapters to hunt down.

Frequently Asked Questions
Can't find your answer?
Contact UsWhat is the Fozmula Mechanical Level Gauge?
A dipstick-style gauge that screws into your tank top and shows fuel level on a graduated scale. No power or electronics. 350mm probe suits tanks up to roughly that depth.
What thread size is it?
DN40 BSP male (1.5 inch). Fits standard Australian tank top fittings. Confirm your tank's thread before ordering.
Will it work with diesel?
Yes. Suits diesel, petrol, and light mineral oils. Not for aggressive chemicals or heavy viscosity fluids.
Can I use it as a backup to an electronic gauge?
Yes. Many sites fit one mechanical gauge alongside electric senders so you can check level manually if the electronics play up or power drops.
What warranty and support do I get?
12-month warranty on defects. Seals and mechanism covered, but physical damage or misuse aren't. For fitment questions or bulk orders, contact sales@goind.com.au or 07 3204 2240.
