Stop leaks and spills from fuel slip tanks

Simple device prevents fuel loss and is good for the environment

Dallas Leduc says a device he has installed in all portable fuel tanks on his southern Saskatchewan farm does exactly what it says it was intended to do — prevents fuel from slopping out through the vented fuel caps, saving fuel and preventing a mess in the back of the truck.

It’s not a life-changing invention says Leduc, who farms at Glentworth about an hour north of the Montana border, but it does keep things cleaner when hauling fuel around the farm. Leduc bought and installed four of the Spillnomore portable tank spill prevention devices (PTSPD).

“There always seemed to be some fuel slopping out of the vented fuel caps,” says Leduc. “When I saw this device made by this fella in northern Alberta, I wondered why no one had come up with something like this before. It works well. It does save a bit of fuel, but mostly there’s no more mess. You can fill the tank, put the cap back on and nothing can splash out, even when you’re travelling over rough ground.” The Spillnomore device was developed by John Banman of La Crete in Alberta’s Peace River Region. For more than 20 years, Banman has been a heavy equipment operator and he’s worked around the road construction, logging and oilfield industries where just about every truck carries a fuel slip tank for refuelling a piece of equipment. And just about every slip tank and truck box has an oily mess from diesel fuel seeping or spilling out of the refill port.

How it works: A stainless-steel insert screws into the fill hole of portable Tidy-style or other make of skid fuel tanks commonly used on farms and construction sites across the country.

After years of working with the mess and fuel loss, Banman figured there had to be a way to prevent leaks and spills. He developed the Spillnomore tank spill prevention device. It is a stainless-steel insert that screws into the fill hole of portable Tidy-style or other make of skid fuel tanks commonly used on farms and construction sites across the country. More information and a video of Spillnomore can be found on the website at spillnomore.ca.

The Spillnomore devices come in two popular diameters — two or 2.5 inches — to fit the most common size fill ports on the portable fuel tanks. There are a couple of other models for specific tank sizes.

The patent-pending secret of the Spillnomore device is a hinged, spring-loaded, flap on the bottom of the insert — the portion of the insert that is actually inside the fuel tank.

Here’s how it works: with the Spillnomore installed in the fuel tank fill port, remove the fuel cap and insert the fuel refill nozzle as per usual. The nozzle will push open the flap at the bottom of the insert on the inside of the tank to allow for the tank to be filled with fuel. Once the tank is full and nozzle removed, the flap closes on the bottom of the Spillnomore insert. Even in rough going, fuel can’t splash up to reach the fill port or vented cap.

Forgot the fuel cap

And the Spillnomore device is particularly valuable if by some chance the person filling the fuel tank forgets to put the vented cap back on.

Forgetting to replace the fuel cap has happened to Banman a few times over his career of working around heavy equipment.

“The first time it happened was probably one of my first jobs in 1978 working at Rainbow Lake,” says Banman. “I forgot to put the cap on the fuel tank and then drove out to the job site. Fuel spilled out, but I did find the cap later and put it back on. It was not just a mess but it also was very embarrassing. It didn’t happen often, but probably four or five times over the years. We often seem to be fuelling up in the dark and that doesn’t help either.”

This Spillnomore device has yet to be installed, but the photo shows how the refill nozzle pushes open the spring-loaded flap at the bottom of the device when the fuel tank is being filled. When the nozzle is removed the flap closes over the bottom preventing fuel from splashing up against the cap.

Even when the fuel cap has been replaced, Banman says sometimes tanks can be overfilled. As the fuel expands it seeps or leaks out through the vented cap. “Because the Spillnomore device extends a few inches into the tank it is difficult to overfill, especially when using an auto-off fuel nozzle,” says Banman. “It automatically leaves room for fuel expansion.”

The Spillnomore devices come in two popular diameters — two or 2.5 inches — to fit the most common size fill ports on the portable fuel tanks. There are a couple of other models for specific tank sizes. Banman says the device has been tested extensively by United Laboratories and passed the grade on all counts. The durability and effectiveness of the flap has been cycled more than 3,000 times with no failures. The materials won’t corrode and once installed there are no leaks.

Price of the Spillnomore ranges from about $100 to $115 each for the two most common sizes. Banman says there is free shipping with orders of two or more units.
