What causes fuel pumps to go bad?
The top reasons for fuel pump failure are contamination, overheating, and the gears in the the fuel pump wearing out over time. Rust, debris, and dirt are three common particles that can somehow enter the gas tank and be fed towards or through the intank fuel filter and possibly into the fuel pump.
What are the signs you need a new fuel pump?
Difficulty starting – If your pump loses power, it will have trouble getting gas to the engine in time for your starter to kick in. You might have to turn the ignition multiple times to get enough gas to the fuel injectors. Engine stuttering – The problem doesn't stop when your motor starts running.
How can I test my fuel pump?
Listen for the fuel pump: Put your ear near the fuel tank and have an assistant turn the ignition key to the “on” position. The fuel pump should make an audible noise if it's working properly. Whack the fuel tank: Have an assistant crank the engine while you hit the fuel tank with a rubber mallet.

Why is microbial growth bad?
On a performance level, it is problematic because microbes produce acids that degrade diesel fuel, clog tank filters due to biomass formations, restrict the flow of fluid, corrode the tanks, and damage engines.
Why is diesel fuel prone to microbial growth?
On a regulatory level, the increase in microbe growth today is the unfortunate result of an Environmental Protection Agency (EPA) mandate requiring less sulfur in diesel to reduce pollutants in the air, but less sulfur in diesel makes the fuel less stable and prone to microbial growth.
How to prevent water fungus?
Use biocides. Biocides will help prevent the growth of bacteria and fungus that can thrive in the water-diesel interface. Once the microbes are present, they multiply quickly and are hard to eliminate. Use fuel treatment with demulsifying properties that separate water from fuel.
What happens when diesel fuel is oxidized?
Oxidation is a chemical reaction that occurs when diesel fuel is introduced to oxygen, and this happens as soon as diesel fuel leaves the refinery. As such, diesel immediately begins to degrade and its lifespan is reduced. Oxidation has a negative effect on both the quality of the fuel and the tank storing the diesel.
Why is diesel fuel stored on site?
With the combination of price and fluctuation factors, the trend has been to purchase diesel fuel in bulk when the price is relatively low and then store it. On-site storage is meant to save on costs and add an element of convenience. There are, however, risks associated with storing diesel on-site, which we will discuss further below.
What happens when diesel is exposed to water?
Threat from Water. When diesel is exposed to water, it causes a hydrolysis reaction, meaning the diesel breaks down due to exposure to water. When condensation accumulates, drops of water can drip from the roof of the storage tank onto the diesel. The exposure to water creates a chemical reaction that — as mentioned — breaks down ...
How long does diesel last in storage?
NFPA 110 refers to diesel “Storage Life,” 1.5 to 2 years. The Standard recommends that, “Tanks should be sized so that the fuel is consumed within the storage life, or provision should be made to replace stale fuel with fresh fuel,” NFPA 110, A-5-9
Reasons not to use old diesel fuel

How does a car start with a fully charged battery?
A fully charged battery is used to crank start a car engine, your electric submersible fuel pump starts pumping fuel at the same time when your car engine is running. If you have a drained car battery, your starter wouldn’t kick in due to the lack of electric power to turn the heavy flywheel, and your fuel pump will not pump fuel to the combustion chambers. Your car’s starter draws a lot of electricity out of the battery, that is why your radio would temporarily be cut off, CD will be cut off, and A/C of your car would pause to blow cool air for a few seconds, everything that uses electricity
How long do fuel pumps last?
Without knowing the type of vehicle it’s hard to give you an accurate answer. Some pumps last as long as the car or truck while others don’t. Honda fuel pumps for instance hardly ever go out. While a Chevrolet truck’s pump usually lasts about 100,000 miles if your lucky. How much gas you keep in the tank matters quite a bit as well because some electric fuel pumps use the gas to keep the pump cool. So constantly having almost an empty tank overheats it and subjects it to sucking in the particles that are in the bottom of the tank. Also changing the fuel filter when your supposed to also makes

How often should I change my fuel filter?
Just look at it this way, the harder a fuel pump has to work, as in, a clogged or dirty filter, the more stress and strain put on pump motor which will kill it much sooner than if no filter clog, it is simple as that, change your fuel filters every 50K or every couple years at most . Here is a little side note, many fuel stations have filters at the pump, which are easy to see, but guess what, you can’t see inside that filter case, so many operators save a ton of money and do not replace fuel filters, hence, the residue that is in every tank gets pumped into your vehicles fuel tank. This I learned from an insider who fills tanks who was blamed for several vehicle break downs with fuel issues. So do not always get no name fuel for a few cents less as example, of which there are plenty attached to quick stop shops as example. Stick with the big name brand gas stations and save big over the long term with less repairs.
What happens if the fuel pump doesn't work?

How Long Does Diesel Fuel Last?
- Studies have determined within 28 days of storage diesel fuel #2 begins to become contaminated and start to degrade. Diesel fuel can only be stored from 6 to 12 months on average— sometimes longer under the best conditions. Generally, to prolong the life of the quality of stored diesel fuel, it should be: 1. Kept cool at around 70 degrees Fahrenhei...
Unfortunately…Even Fresh Fuel Can Be Contaminated!
- Clogged filters and rust on the filler cap are usually the first visible signs that you’ve got these organisms in the tank. But even a quick glance at your fuel can tell you if something’s wrong. All of these samples (picture below) were taken from the middle of diesel tanks with various states of overgrowth. If left alone, these organisms will continue to grow and you run the risk that your ge…
