Fuel Tank Equipment FAQs
Yes, the fitting kit comes complete with a 1/4 turn isolation (or shut off valve) so maintenance can be carried out on the fitting kit or supply pipe – even when your heating oil tank is full of oil. To find out more about our tank fitting kits, go to our tank equipment page, or contact one of our friendly team members over the phone, or by email. We’ll be happy to help you find the exact fuel tank equipment you’re looking for.
No oil tank should be fitted with sludge cock or valves – UK regulation rules out this option for a multitude of reasons. The primary reason for this ruling is the added risk of spillage caused by the addition of any openings below the maximum level of oil and fuel tanks. Spillages and leaks can be highly detrimental to the environment surrounding a compromised tank, and very costly, so all necessary steps should be taken to avoid them.
When inspection or contaminant removal is required, this should be done through the inspection aperture, and by an OFTEC licenced technician.
There are a number of precautions and measures you should consider prior to and when installing a sight gauge, including:
- Pressure – consider the amount of pressure likely to be produced within your tank, and the amount your sight gauge is able to withstand.
- Port availability – where are your existing ports located? This will impact the type of sight gauge you are able to install.
- Sight gauge quality – compare sight gauges carefully. Ensure they are durable and check their exact specifications.
- Ease of installation
- Ease of maintenance
- Oil fluctuations – if the level of oil in your tank fluctuates frequently, this should be taken into consideration. Bullseye sight gauges are a better fit for those with more consistent levels, whilst columnar gauges may better serve a fluctuating tank.
- Additional hardware and installation requirements.
A two pin type socket is used to enable the tank to connect to a SecuTech LRC Overfill Prevention System. This system is commonly used by fuel delivery drivers, and should not generally be used by the consumer.
The liquids that can be monitored used the Apollo tank guage includes stored diesel, kerosene, gas oil types A1, C1, C2 and D, alongside water, and a variety of chemicals. Apollo tank gauges may also be suitable for use with solid materials.
For more exact specifications, or for further clarification on whether or not the Apollo is a suitable gauge for your fuel, speak to one of our friendly team members over the phone, or through email. We’ll be happy to help. Alternatively, you can contact Apollo directly through their website.
The need to replace filters will depend upon a number of factors: the recommended period between filter replacements, the brand of fuel station/filter, and the type of fuel station you have installed. Generally, oil filter cartridges do not require overly-frequent replacement and are most often changed by registered technicians during annual oil tank and equipment cleans, and services where undertaken.
If you are experiencing cartridge clogging with a relatively new filter, this may be corrected within the oil tank, rather than at the point of filtration. If you require further advice relating to oil tank filters and cartridges, contact one of our friendly team members over the phone, or through email today. We’ll be happy to help you.
A sight gauge is a small tube typically connected to the bottom of an oil tank line using a feed pipe and attached to the side of the tank (though there are different varieties available). Sight gauges use gravity to provide a visual guide as to the amount of fuel left in a tank.
A sight gauge may be fitted to an oil tank so long as its fitting does not involve the creation of a new valve below the level of maximum capacity. UK regulation rules out this option for a multitude of reasons. The primary reason for this ruling is the added risk of spillage caused by the addition of any openings below the maximum level of oil and fuel tanks. Spillages and leaks can be highly detrimental to the environment surrounding a compromised tank, and very costly, so all necessary steps should be taken to avoid them.
It may sound obvious but it’s helpful to know your starting point. If you’re unsure of the size of your tank and its capacity you should find a label on the tank that tells you. On more recent tanks, it may be on the front or side.
To measure, many tanks have simple float gauges or sight level tubes that allow you to keep an eye on your oil level.
If your tank has a digital monitor that plugs into an electric socket inside the house, such as an Apollo or Watchman, ordering when the digit reaches 1 or 2 (1 or 2 bars) is usually the ideal time.
Most systems are designed to flash at either Level 1 or Level 2. When the monitor first starts flashing at these levels, you still have quite a bit of oil left so there’s no need to panic and turn off your heating – the flashing is merely a visible reminder to place your order.
If your tank has no gauging system, or you want to double-check the accuracy of your gauge, an alternative basic method to monitor how much oil you have left is to dip the tank.
To avoid contamination, make sure you use a designated dipstick that is kept clean and used solely for your oil tank.
To measure your tank manually, take the cap off the top of the tank, which is where the fuel goes in, and put the dipstick right down to the bottom of the tank. When the stick is withdrawn, the oil will leave a mark on the stick consistent with the level of oil. When your tank level gets down to around the last 12 inches (approx. 30cm), we recommend it’s time to order your fuel.
Fuel tanks, and oil tanks, are highly dependent on filter systems to ensure minimum contamination and debris are present in fuel during delivery and dispensing. Contaminated fuel is known to cause damage to both fuel pumping equipment, and to the engines and inner workings of the machines and vehicles to which it is delivered. These filters are known to ‘catch’ dust, debris, algae, and other larger impurities.
Fuel tank filters are one of the most effective ways to ensure your fuel or oil, is dispensed in the best possible condition, helping you maintain every part of your machinery.
There are a number of fuel gauge types on the market, but all should serve as an effective indicator (digital or visual) of oil or fuel levels remaining within a tank. There is no one ‘best’ type of fuel gauge – so it’s important to take into consideration your specific requirements during the browsing and selection process.
You should consider the maximum capacity of your tank, the amount of accuracy you require, your budget, and the way in which you would like to power your gauge – if at all.
Common gauge types available include:
- Floats – a simple mechanism giving an estimated reading of tank contents through an analog screen.
- Sight gauges – give a literal visual indication of the amount of fuel remaining through pulling fuel into a clear tube affixed to the side of the tank.
- Ultrasonic gauges – use ultrasonic waves to measure oil levels, but typically require a hole to be drilled in the tank. This may go against regulation in some local authorities, depending on the hole location.
- Hydrostatic analog gauges – use a pressure sensor to measure the weight of the oil or fuel remaining in the tank. Produces analog results.
- Hydrostatic digital gauges – use a pressure sensor to measure the weight of the oil left in the tank. Produces accurate readings, which can typically be displayed in litres, mm or %.
