Whenever I turn on my 2000 Ford ranger gas is pouring out of the top of the tank drivers side.

 

Cool. You planning on fixing it?

 

Welcome to the forum

Best bet is to unbolt the bed, 6 bolts, t-55 heads
Unscrew the filler, 3 screws, phillips

Then tilt the bed up in the front so you can access the top of the gas tank, there is a broke hose or connector

If you want to slide the bed back(or remove it) then you also need to unplug the tail lights

Dropping the gas tank requires a shop with a lift and transmission jack to hold the tank, as the wires and hose(s) are tight so you must be able to hold the tank up while you get your hand in there to unplug or plug then back in, or you will do more damage then you have now, lol
