- Terrain and weather – mpg drops in cold weather or mountainous areas
Understanding these factors helps set realistic mpg expectations.
Gas Tank Design and Placement
In addition to capacity, it’s important to understand the Jeep Wrangler’s gas tank design and placement:
Construction
Wrangler gas tanks are made from High Molecular Weight, High Density Polyethylene (HMWHDPE). This durable plastic material is corrosion and impact resistant.
Shape
The tanks have a rounded, oblong shape that follows the Wrangler’s underside contours. This helps provide sufficient capacity within size constraints.
Location
The gas tank is mounted behind the rear axle using steel straps bolted to the frame. This central location helps maintain optimal front-to-rear weight distribution.
Protection
Shielding like skid plates and impact bars are used to protect the Wrangler’s vulnerable gas tank during off-road driving. This prevents punctures or damage from rocks, obstacles and debris.
Fuel Pump
An electric fuel pump mounted inside the tank delivers gasoline to the engine at the required pressure and flow rate. It is immersed in the fuel to stay cool.
Filler Pipe
This connects the gas cap to the tank opening. It is made of steel tubing and includes a shut-off valve to prevent overflow. The filler pipe is accessed via the fuel door.
Maintaining Your Jeep Wrangler Gas Tank
Proper maintenance is crucial to keep your Jeep’s gas tank and fuel system operating safely and efficiently. Here are some tips:
Inspect Fuel Tank Straps
Check the steel straps that hold the tank in place for rust and damage during routine servicing. Loose straps can cause the tank to drop and be damaged.
Replace Fuel Filter
Replace the fuel filter at recommended intervals, typically every 20k-30k miles. Clogged filters strain the fuel pump and reduce performance.
Keep Fuel Cap Tight
Always tighten the gas cap securely after refueling. Loose or missing gas caps allow fuel vapors to escape and trigger the check engine light.
Clean Filler Pipe Screen
Use a small pipe brush to gently clean the filler pipe screen when you change the fuel filter. This removes grit and sediment.
Check Underbody Shields
Inspect underbody shields and skid plates for damage after off-road driving. Bent or missing shields can’t protect the gas tank from impact.
Repair Tank Leaks
If you smell gas or see leaks, have the tank inspected immediately. Even minor leaks are hazardous and require professional repairs.
Proper gas tank maintenance keeps your Jeep running smoothly mile after mile. Follow the manufacturer’s recommendations for scheduled upkeep.
