|The priming lever on most mechanical lift pumps is often very small, sometimes hard to reach and occasionally won't work if the engine's cam is compressing the pump's spring. However, an external priming pump has none of these disadvantages. Some Caterpillar engines are equipped with high-volume plunger pumps that work extremely well, but they are the exception. Reverso, a manufacturer of a variety of marine products including fuel polishing and oil change systems, offers a manual priming pump that's up to the task. The plunger-type device pumps .85 ounces per stroke, and it's equipped with a large red locking collar to secure it when not in use. Working pressure is up to 100psi. Fuel passes through the pump unhindered during normal engine operation, and the pump is certified for use with up to 100 percent biodiesel. It's available in either half-inch female threaded or JIC flare fittings for $85 or $115 respectively. Visit www.reversopumps.com.

Struggling Barge Now Completely Underwater Off Miami Coast

MIAMI (CBSMiami) – A foundering barge is now completely underwater 20 miles off the coast of Miami.
In the afternoon, photos from boats and planes monitoring the progress of the doomed barge show it standing up in the water, perpendicular to the waves, like a giant exclamation point. Many of the containers have fallen from the barge, and are in the water surrounding or are already headed to the bottom.
“The barge has flipped over and the stern is in the air, and we are monitoring the situation, helping to see if we can expedite the sinking of this barge,” said Capt. Chris Scraba, commander of Coast Guard Sector Miami.
The Coast Guard has been working with the barge and the tug that had
been towing it for 3 days, after the tug Sante Tio lost power due to bad
“It appears at least half the barge compartments have been compromised and their flooded.” Cory Offutt, owner of Tow Boat US Miami, told CBS4′s David Sutta as they flew over the scene Wednesday.
Salvage companies from across South Florida have tried to save it but in the end couldn’t. “It’s pretty impressive that it’s still floating, ” Offut said. “It’s amazing the owner is going to lose his barge and his business. It’s dramatic in a lot of different ways.”
” By sinking the vessel out in 2 thousand feet of water,” Capt. Scaraba said, “we have done the best we can to ensure the environment is safe, and that there is no damage to the environment.”
The cause of the stranding is still under investigation, but the tug and barge began the trip in Haiti, and it’s there has been speculation the tug could have taken on contaminated fuel that fouled it’s engines.
The barge has been valued at $350 thousand.
How dirty is your fuel? Unfortunately, there is not single answer this question.
The time it takes before the filter element reaches max dirt load can vary from 10 minutes to 300 hours. It is completely dependent on the dirt load and type of contamination in the tanks.
Often we find masses of solids settle in the bottom of tanks, and these can clog elements, quickly. It is for this reason that we have the 60 micron Stainless Steel element. This can simply be backflushed, a procedure detailed in the operating manual, and available in Product Literature.
When clogged, the stainless steel element can be removed, and cleaned for reuse. When using our standard 10 or 30 micron paper elements the number of times it can be backflushed, depends on the type (sticky or not) of dirt lodged in the element.
In some installations in the U.S., where the fuel is like water, we have customers that replace the filter element only once per year in a permanent installation.
For mobile tank cleaning where the tank is dirty to begin with, we recommend the use of the 60 micron Stainless Steel element. This can be removed and cleaned many, many times. It is best to have two stainless steel elements, so that the machine can continue to work during the element cleaning process.
Once the 60 micron filter comes out clean, then you can switch to the 30 micron paper element and continue the process. This will prevent the expenditure of a large number of paper elements.
How can we know that diesel is flowing from inlet to outlet? Is there a minimum reading on the vacuum gauge to indicate that?
You cannot tell from the vacuum gauge if fuel is flowing. The pumps are capable of creating a vacuum in the filters when fuel is NOT present. One method for determining if flow is present is to check the discharge hose. When you first start the unit, you listen to the pump. Depending upon the length of your inlet hose, and the height of the suction lift, it will take from 30 seconds up to a minute to take suction. As liquid reaches the pump you will hear a change in pitch and volume from the pump. At the same time you will see the black needle on the vacuum gauge move to the left. How far this moves is a function of the length and diameter of the hose, as well as the height of the suction lift. The lower the number the better, as the gauge reads the total system vacuum, and not the condition of the filter. The best method for determining flow, and measuring it, is to install our optional flow meter to the outlet of the system.
How do I prime the fuel system?
If the pump does not take prime in the first minute, or this is the first time the unit has been run, it may be necessary to prime the system. There are several ways in which to do this. Perhaps the easiest way to do this is to attach a very short hose to the inlet of the system, and place the hose into a container of diesel fuel, start the system, and allow the pump to run until the 2-3 gallons of fuel have been moved thru the system. If this is not possible, remove the lid of the filter, remove the filter element and spring cage. Instructions for removing the lid, and filter element are contained in your operating manual. Manually fill the filter housing with clean diesel fuel. Replace the filter element, and spring cage. Re-install the lid and tighten lid screws to proper torque. Proper torque specifications are located in your operating manual. It is suggested to install a foot valve, check valve, or non-return valve to ensure that system maintains its prime after initial prime.
Is there Dry Run protection for the pump?
The pump is not equipped with "Dry Run" protection. The operator must pay attention to the machine. Normally, our systems are used to circulate fuel in a tank - pull fuel from the tank, and return it to the same tank. In this scenario, it would be very unlikely that the pump would ever run dry. If your application is different, (such as pulling fuel from multiple tanks or using the system as a clean fuel dispenser), then running the tank / pump dry is more likely.
What is the high-pressure alarm?
The high-pressure alarm is used in situations where the discharge line can be closed with either a valve or hose kink. This will protect the system and prevent hoses bursting which could leak fuel. The high-pressure alarm is used on units equipped with a gear pump. This protects the pump from damage due to high pressure caused by closing the discharge or accidentally blocking the hose. It prevents excess current in the motor. Units equipped with the vane pump do not have this safety as the vane pump is equipped with a built in pressure bypass.
Question: I have installed four Separ Filters on two haulers and two loaders. The filters get stuck very easily and fast. We even have to take off the valve in order to liberate the bowl. Should we clean the filter more often?
Answer: If the filter is equipped with a vacuum gauge you can monitor it and do a back flush at about 8-10 inches of vacuum. This will extend the life of the filter. There are two other options that you may want to consider as well.
1. Clean the fuel with a portable fuel polishing/dispensing cart when the equipment is fueled. Click here for more info.
2. Install a second filter as a strainer with a 60 micron cleanable stainless steel element in from of the primary filter. This will have no effect on the restriction to flow and will remove much of the heavy dirt and water before it get to the primary 30 micron element, as seen on this John Deere combine.
