I could use some help here. I replaced my front tank on my 92 F-150. After replacing it i went to start it and got nothing. The rear tank was working fine until all this and now im not getting anything from anywhere. Neither the front tank (has 5 gallons in it) Nor the back tank (has 2 or 2 gallons in it) seem to be sending fuel to the motor. Do i have something in the lines? Any ideas?

need more info was it running befor you replaced the front tank? did you replace the fuel pump in the front tank? why did you replace the tank?

go back over everything and make sure everything is hooked up and tight, it could be something as simple as a loose wire (very dangerous if near the tank) or see if you have an automatic fuel shut off ( when pressure drops it shuts off gas flow).

If were just throwing stuff out their. I would start at the inertia switch. It’s a fuel cut-off switch (resetable) in case of an accident located behind the brake pedal mounted on the fire wall. They do trip on shorts and light impacts, even had one trip when a friend slammed the truck door.
