How to Fix a Leaking Gas Tank in a Boat
- 1). Park your boat and make sure that the engine is shut down. Let the engine cool off for several minutes. Locate the gas tank and fuel delivery system and examine for holes and rust formation. Check the gas tank hoses for leaks and make sure they are connected properly. Unscrew the bolts of the hoses using a wrench and remove them one by one. Install new ones with the same size and screw back the bolts tightly.
- 2). Apply strong sealants and adhesive directly to cover the gas tank holes. Test if gas continues to leak. Replace the tank with a new one if the problem is not addressed.
- 3). Shut off all fuel hoses. Drain the fuel from the old tank by pumping it out with big suction hoses directly to a large container. Start the engine and burn off any remaining fuel. Make sure that materials like cigarette lighters and matches are kept away when draining the fuel.
- 4). Unscrew the bolts of the tank's safety brackets with a wrench. Pull out the brackets and remove the gas tank carefully. Make sure to remove any remaining fuel before disposing properly.
- 5). Install the new gas tank and make sure it is fitted perfectly. Screw back the bolts of the safety brackets tightly. Move the tank side to side to make sure that the installation is stable.
- 6). Reconnect all hoses and install a new fuel gauge sending unit. Refill the tank with fuel and start the engine for several minutes. Inspect the tank and hoses for leaks. Test-drive the boat for a few miles while noting whether you're getting the proper fuel consumption per mile.
