Jeep Fuel Tank
There are chances that the bolts that hold the fuel tank in place are rusted, and that needs oil that is designed for rusty nuts and bolts. You may break some bolts, but any auto parts suppliers should have the right grade and size of bolt. Usually, the most common method of securing the fuel tanks to vehicles is straps bolted to the frame or crossmember that run under the tank and that you can secure it to the vehicle. The shield does not only holds the tank in place but also protects it form the damage during the off road excursions. It can also retain dirt and moisture which gives rust a place to start.
There are certain steps and directions that should be followed in installing and replacing your fuel tanks. You just have to familiarize yourself with them. But if you got no time for this, your professional mechanic can do it for you.
