How do I get gas out of gas tank on a 1998 Jeep Grand Cherokee Laredo inline 6
No job stated, so cant help much. CONTEXT and symptoms do let me help 100x better, for sure.
the fsm covers this.
some cars have anti siphon valves in filler.
so?
on my car is used the fuel pump in the car to pump it down.
but that takes a good fuel pump.(and make no sparks.......)
the fsm covers this. read that. ZJ book, free

is this a pump problem or gauge level problem
or EVAL issue. cant guess that. no way.
and the job in the FSM , is based on that.
ill assume the pump is dead 0 psi cranking for 3 seconds.
and had 12vdc to it , during the cranking event.
above link
open chapter fuel systems
then PDF page 10
there it is , the factory methods
step 11 is tricky ,read that first.
step 14, insert fuel draining station hose to the filler hose,
then pump it down
if DIY, (i have my own pumps, in a box) but you can use SOP
syphon hose now. avoid, drinking fuel. benzene is toxic, to max.
SOP. standard operating procedure of any gas thief (lol)
or connect hose to the filter pipe input
then to external gas tank
and hot wire the tank pump.
ways, all. (recap)
SOURCE: P0456 OBD code just appeared on a 2004 Jeep Grand
That code definition is (evaporative system small leak detected). One of the most common reasons for this code is a faulty gas cap. The evap system is strictly designed to trap fuel vapors in the tank and not allow them to scape into the atmosphere. The vehicle keeps a constant vacume on the tank and when it is unable to hold that pressure it will set the code you have. Try buying a new gas cap-thats a cheap start-clear the code and see what happens. If the light comes back on you will have to bring it to a repair shop where they will tap into the Evap system and force smoke into it. They will then observe the Evap hoses and wherever it leaks smoke will be your problem.
