How do you drain the gas out of a 94 with a single tank. I think the gas is old it keeps shaking when I drive it like it doesn't wanna go, but the trans shifts fine.

 

Get an old electric fuel pump with some hoses on it and connect it to a battery while you drain the old gas out, you know what i mean

 

take the fuel line loose and jumper the fuel pump connector so it has power full time..it will drain teh tank...

you can either jumper the connector under the truck or the Diagnostic connector to test the fuel pump...

 

I prefer just doing it at the diagnostic connector. Less chance of spark ignition.

 

What you mean diagnostic connector ?

 

there is a Diagnostic connector under the hood that you can jumper to make the fuel pump run...

 

id disconnect the fuel line from the filter, run it into a jug. then pop your hood take off your fuel pump relay take a paper clip and use it as a jumper. make sure the key is on.

 

yea or do it that way probably a little easier
