Since diesel tractor engines work off high pressure, if air gets into the fuel line (like when you run out of fuel) the tractor may no longer want to start up. (If you do not see smoke when you crank the engine, you probably have air in the line which is preventing the fuel from getting to the engine.

If your tractor will not start and you do not see smoke (and sometimes even when you do) when you are cranking it, then you may have air in the fuel lines (see below question and answer on how to fix). If your tractor will not start, you do see smoke while cranking, and it is fairly cold outside (<50 degrees) then it might just be the temperature. Diesel engines are notably harder to start the colder it gets outside, but this is why most diesel engines come with "glow plugs".

No. You do not pay the diesel fuel tax when purchasing dyed diesel fuel. However, dyed diesel fuel should only be used to operate vehicles or equipment off-highway. You will be subject to the tax and a penalty if you operate a motor vehicle on a highway in California with dyed diesel fuel in the supply tank. Yes.

You may submit your refund claim and registration application at the same time, though the registration process may slow the handling of the claim. In addition, you will be asked to submit a completed Diesel Questionnaire.

There is no difference between fuel (heating) oil and off road diesel. However, road diesel has lower sulfur and is clear. Heating Oil and off road are dyed.

Between 30 June 2000 and November 2007, the Queensland Fuel Subsidy Scheme applies to all fuel purchased in Queensland. However, from 1 July 2000, the Commonwealth assumed full responsibility for the payment of rebates to off-road diesel users as part of the National Tax Reform arrangements. From this date, the Queensland Fuel Subsidy no longer applied to diesel purchased for an off-road purpose.

There is no definition of premium fuel, so the term eally means nothing and is over used by suppliers. For a descrition of the characteristics proposed for "premium diesel" see this Cheveron bulletin. Cummins says that fuel additives are not needed in their engines.

Emissions results do vary between engines and test equipment, but in our tests on an early 80's VW turbodiesel, opacity (which is used as an indicator of particulate emissions) was reduced by about 50%, compared to premium diesel fuel. Other EPA regulated emissions were about the same for all the fuels tested. Power was equal to premium diesel that test. We find no difference power while driving, between diesel and SVO/WVO, as long as the filter is clean and the SVO is heated.

Children are more susceptible to air pollutants because their lungs are still developing and their airways are narrower than those of adults. In addition, children often play outdoors during the day and may be more exposed. Children raised in heavily polluted areas have reduced lung capacity, prematurely aged lungs, and increased risk of bronchitis and asthma compared to peers living in less urbanized areas.

People run long pressure lines to help smooth out the pressure pulses from the pipe. At max revs the pressure pulses are very strong and can foam the fuel causing a lean fuel mixture. A pressure chamber accomplishes the same thing without a tangled mess of fuel tubing. I am using the big Kyosho fuel filter with the mesh screen taken out as a pressure chamber. I run my fuel line 8in (20cm), which is the maximum.

Biodiesel is a great solvent and it will degrade natural rubber fuel lines, which are sometimes found in older vehicles. All newer cars have synthetic rubber fuel lines, which have no problem transferring Biodiesel. If you have an older vehicle and run Biodiesel you can determine if you have natural rubber fuel lines because the lines will appear to be sweating after a few weeks of use. Simply replace your fuel lines with synthetic rubber ones and your vehicle is ready to go.

Well, you could mix it yourself (as mentioned earlier), but there is a company in California called Aero Dyne who sells pre mixed diesel in small, or large quantities for a very reasonable price--and how I wish I could buy their fuel here :-(

You may have the most advanced high performance diesel engine ever made, but, if your fuel is of poor quality or contaminated, you have a poorly performing engine.

Yes, The EPA has finalized similarly stringent standards for non-road diesel fuel that will be phased in over several years. In California, there is no distinction between on-highway and off-highway diesel fuel. The 2006 California diesel fuel regulation will cover off-highway diesel as well.

The use of ProFuelX-2? is recommended in each tank of gasoline or diesel fuel used in the vehicle's engine. Yes. ProFuelX-2? is completely soluble in all oil based additives, such as stabilizers, anti-gels and fuel conditioners. Yes. ProFuelX-2? Technology accelerates the combustion process and significantly reduces the smoke and particulate emissions from diesel engines. It improves cetane number, reduces engine noise and improves fuel economy.

There are no harmful effects of over treating gasoline and diesel fuel with ProFuelX-2?. However, ProFuelX-2? benefits do not increase with over treating. Yes. During the production of low sulfur diesel, desulphurization processes at the refineries reduce the fuel lubricity. ProFuelX-2? enhances fuel lubricity and is the perfect product for use in low sulfur diesel fuels.

Sulfur content, Cetane number (ignition quality), cleanliness, lubricity, low-temperature operability and stability are the diesel fuel requirements of principal concern to you. With the introduction of the 2007 model year, diesel powered vehicles have to meet stringent emissions limits. The equipment used by vehicles to meet those standards depend upon a fuel with very low sulfur content, 15 parts per million (ppm) or less, referred to as Ultra Low Sulfur Diesel (ULSD).

Ultra Low sulfur diesel fuels (less than 15 ppm) are required by federal regulations for 2007 model year highway vehicles to ensure that these vehicles will meet emissions standards to improve the quality of the air we breathe. In California, other properties of vehicular diesel fuel are also controlled to help reduce smog.

YES. The FUEL OPTIMISER also offers substantial savings and a drastic reduction in NO emissions and soot.
