Jeep TJ Fuel Pumps
The fuel pump is an important part of your Jeep TJ Wranglers internal combustion process. Some pumps are low-pressure mechanical devices attached to the front or rear of the Jeeps fuel tank, while electric fuel pumps are affixed to the inside of the fuel tank. Its important to understand how fuel pumps work, how to maintain them, and what signs to look for when you may need to replace the pump entirely.How do fuel pumps for the Jeep TJ work?
Your Jeep Wranglers engine burns a precise mixture of air and fuel. The combination of these two elements is known as the air-to-fuel ratio. The better the oxygen and fuel in your Jeeps engine mix with one another, the more fuel-efficient the vehicle will be. This increase in efficiency is likely to give your Jeep better mileage as well. The pump of your Jeep Wrangler consists of several parts that work together to increase the vehicles performance.
- The fuel pump of your Wrangler takes the gas out of the fuel tank, moves it through a pipe, and deposits it into the carburetor.
- A solenoid attracts a rod made of iron, which in turn creates the pull that draws the fuel out of the TJs fuel pump. The rod follows the solenoid and pulls down on the pumps diaphragm, drawing fuel into the main chamber of your TJ Wranglers fuel system.
- Fuel and air are both filtered to remove debris and contaminants prior to delivering the fuel mixture to the carburetor.
Because the fuel pump is one of the most important parts of your TJ Wrangler and its fuel system, its essential to recognize the early signs of fuel pump failure. Knowing when the pump on your TJ is starting to falter will allow you to replace it with a working unit as soon as possible. Attempting to drive your Jeep with a malfunctioning fuel pump could result in a serious decrease in performance or total failure of the TJs engine, leaving you stranded on a trail. If you see any of these common signs in your Jeep Wranglers current pump, you should seek a replacement part immediately.
- If your Jeep Wranglers engine starts to sputter when you reach high speeds, the fuel pump could be in bad shape. This sputtering occurs because the pump is having trouble supplying your TJs engine with fuel at a consistent rate.
- A temperature gauge that rises above normal levels could point to an issue with your Jeeps pump. A Wrangler that runs hot could mean the motor on your fuel pump is having trouble functioning and needs to be replaced.
- Your TJ should exert a certain amount of pressure when it is working properly. If the pressure gauge for your pump shows less-than-ideal readings, you may need to replace it.
- Your Jeep TJ should be able to go uphill or pull heavy cargo with relative ease. If it is struggling to do this, it means the fuel pump is failing and cannot keep up with the increased demands.
