Fuel Transfer Pump
Many individuals who are on the road a lot have chosen to have an auxiliary fuel tank on their vehicle. Generally, large semi-diesel trucks, some pick-up trucks and a few motor homes as well as other motorized RV’s are seen on the road these days with auxiliary fuel tanks. Having an auxiliary fuel tank allows the driver to increase their driving range before they have to stop and fuel up again. Without an auxiliary tank, the driving range is generally limited to around 300 miles before the need for the next fuel up.
There are actually several more reasons to add an auxiliary fuel pump to your diesel pick-up truck too. If you are going on a long trip across the country you can fill up your tanks whenever you find the best prices for fuel. Prices can vary from one state to another so this really frees you up from paying high prices. The only worries you will have about stopping are to get something to eat and use the restrooms. Whenever gas stations are few and far in between, having an auxiliary fuel tank can be a life saver because there is a greatly decreased likelihood of running out of fuel.
A fuel transfer pump is essential when you have an auxiliary tank because that is the device that will transfer the fuel from your auxiliary tank into your main fuel tank. An electric fuel transfer pump supply line is normally connected from the auxiliary tank to the vent hose you the main tank when you have a fuel transfer tank installed. Once the main tank is empty, the operator can turn on the fuel transfer pump or you can have a set up that does it automatically.
Some people would rather have an electric fuel transfer pump rather than a switch valve. When they have an auxiliary tank an electric transfer pump will make things a lot easier. It will also be more reliable than using a switch valve to get the fuel from the auxiliary tank. Some of the better electric fuel transfer pump systems have a "control panel." They typically have a digital readout on them now. The amount of fuel in each tank will be shown and the fuel transfer is done automatically whenever it is needed. Both tanks are labeled on the control panel as "main and auxiliary." The whole system is set up so that your fuel gauge registers how much fuel is in the auxiliary tank too.
When your fuel switch is on "main", the fuel in the main tank is used. When it is on "auxiliary", the fuel is used from that tank. Having an auxiliary fuel tank and fuel transfer pump is your back-up for when you run low on gas and are in an unfamiliar area with no idea where the next gas station is.
Fuel transfer pumps can go bad just like any other fuel pump can go bad. You will know right away when your fuel pump quits working because you will run out of fuel. When this happens you will have to determine which fuel pump is bad and replace the appropriate one.
Of course there are other types of fuel transfer pumps. Some are used to transfer large amounts for fuel for certain companies that use a lot of it in their daily business operations. For instance, a large farm may have need of transferring large amounts of fuel from one storage tank to use on many devices, such as for different tractors or other such equipment. If you have the right kind of fuel transfer pump, you can efficiently and safely transfer large amounts of gasoline, diesel, kerosene, solvents and heptane.
