How do you take off gas tank on f150?

Answer 1

IF THE TRUCK IS FUEL INJECTED YOU HAVE TO RELEAVE THE PRESURE IN THE SYSTEM. START THE ENGINE LOCATE THE FULE PUMP CUT OFF SWITCH. THE SWITCH IN A 88 F150 IS LOCATED JUST BEHIND THE LEFT SIDE OF THE BREAK PEDDLE IT HAS A RED BUTTON ON THE TOP OF IT. IN THE SLOT PRVIDED POP THE BUTTON UP WITH A SMALL SCREWDRIVER THIS SHUTS OFF THE FULE PUMPS. LET THE TRUCK RUN UNTIL IT SHUTS OFF ON ITS OWN, WHEN IT SHUTS OFF TRY STARTING THE TRUCK FOR A FEW SECONDS THE TRUCK WONT START BUT THIS RELEAVES ANY PRESURE LEFT IN THE LINES. NEXT DISCONECT THE NEGATIVE TERMINAL FROM THE BATTERY. SIPHONE ANY GAS IN TANK OUT INTO A SUITABLE COTAINER. PUT A FLOOR JACK UNDER TANK TO SUPPORT IT LOSSEN THE FILLER HOSE FROM THE TANK. LOSSEN THE BOLTS HOLDING THE STRAPS AROUND THE TANK, AND REMOVE THE STRAPS. SLOWLY LOWER THE TANK. ONCE ACCESABLE UNPLUG THE WIREING HARNESS FROM THE TOP OF THE TANK THEN REMOVE THE FULE LINES GOING INTO THE TANK AND THE SMALL VENT HOSE. THE FITTINGS ON THE FUEL LINES ARE HELD ON WITH A CLIP PRY THEM OUT WITH A SCREW DRIVER AND WORK THE FITTING UNTIL IT SLIDES OFF TURNING AND PULLING THIS MAY TAKE SOME EFFORT. ONCE LOSE, AND SLIDING OFF LISTEN FOR THE RELEASE OFF ANY PRESURE THAT MAY STILL BE IN LINE TO GO AWAY. WITH A SHOP RAG AROUND LINE REMOVE IT SOME FUEL WILL COME OUT OF LINE BUT NOT VERY MUCH. ONCE THIS IS DONE REMOVE THE TANK. ITS A GOOD IDEA TO MARK ONE FUEL LINE SO YOU KNOW WITCH ONE GOES WHERE WHEN YOU TRY TO REINSTALL THE TANK INSTALATION IS THE OPPOSIT ONCE TANK IS BACK ON PUT GAS IN IT. RECONECT THE BATTERY, RESET THE SHUT OFF SWITCH BY PUSHING DOWN THE RED BUTTON AND STARTER UP. HOPE THIS HELPS
