Fuel Cell GroundingIn addition to wiring the power needed to run an electric fuel pump, a fuel cell should be grounded to the frame. This will prevent buildup of static electricity due to the fuel sloshing within the foam. Such buildup could lead to a fuel explosion.
MaintenanceSome fuel cells can be affected and may degrade with the use of gas additives and by long-term storage of additives. Be sure to check with the supplier if any such precautions apply to your fuel cell.
Additionally, the cell should be inspected periodically to ensure the seals and gaskets are in good shape and that the safety check valve is operating properly. The pickup screen that filters out any debris in the tank should be cleaned or replaced as needed. The typical lifespan of a plastic-type cell is about 3 years and bladders should be replaced within no more than 5 years.
Depending on your requirements and vehicle setup, a fuel cell may provide you with safe fuel storage along with lighter weight or increased traveling capacity. Hopefully, we've provided you with a little more information to improve your fuel cell knowledge
 When mounting your cell, choose...  When mounting your cell, choose a location that is well protected from impact or contact with outside obstacles. Consider how much your chassis may bend during off-road use and if that may flex and fatigue your cell. Aluminum cells are more vulnerable to this possibility than the steel or plastic varieties. |  Premade mounting straps can...  Premade mounting straps can be purchased for many of the polyethylene fuel cells. These fit snugly and can speed up fabrication and installation time if you prefer not to build your own retention straps. |  Here is a rear view of a plastic...  Here is a rear view of a plastic cell that uses a dropped sump. Two outlets are provided at the low point on the cell. One outlet serves as the fuel supply and the other as a fuel-return port. |
 The outlet connections on...  The outlet connections on fuel cells are AN-type fittings. You can purchase a wide variety of aluminum or steel adapters, elbows, and other fittings to mate to your fuel feed and return line (if needed). You can mate to braided-steel flex hose or to more standard rubber hose, based on your use and cost considerations. |  Rollover check valves can...  Rollover check valves can be purchased to stop the flow of gas out the top vent outlet should you put your rig upside down. This valve from RCI is a bulkhead-mount unit that installs right on the top wall surface of the cell. You can also purchase in-line versions with AN-type fittings. |  Here is the fuel feed and...  Here is the fuel feed and return plumbing on a typical plastic fuel cell. This owner chose to use adapters to reduce the fuel line size to more appropriately match his engine size and plumb to the lines with braided-steel hoses. |
 To ensure reliable fuel delivery...  To ensure reliable fuel delivery with your 4x4 at any angle, you can add several of these Walbro fuel pickups from Auto Performance Engineering to front and rear locations in the fuel cell. With their special design they can reliably supply gas from any one of the submerged pickups regardless of the submersion condition of the others. |  The outlet connections on...  The outlet connections on fuel cells are AN-type fittings. You can purchase a wide variety of aluminum or steel adapters, elbows, and other fittings to mate to your fuel feed and return line (if needed). You can mate to braided-steel flex hose or to more standard rubber hose, based on your use and cost considerations. |  Here you can see the vent...  Here you can see the vent outlet on top of this cell. Some rollover valves are designed to operate best when fully inverted and not so well when on their side. A vent hose can be added that runs a loop under the cell and up the other side, terminating in a small air breather. A plumber's loop such as this can help stop fuel leaks when your rolled rig is at any attitude, not just fully wheels up. |
