90-94 LS400 Fuel Pump Removal
Anybody remove the fuel pump and installed a new one?
If you did, did you remove all the fuel from the tank before? or did you leave the fuel inside and just remove the fuel pump?
Here is Lextreme's website on how to remove the pump, but doesn't state removing fuel from tank..

check out how the fuel tank is set up click here:

Factory Lexus Manual states removing fuel from tank before replacing fuel pump, but doesn't explain how.
Tried siphoning through gas cap vent with a 3/8", 1/2", 1/4" hose and all did not work..seems to get stuck all at a certain point...
Any ideas anybody?
Relieve pressure from tank? Methods of removing fuel from tank?
Thank god you don't have to drop the entire tank though.

I've done fuel pumps before and I always leave the gas in there. Just give some floor jacks to hold it up and lower it down slowly and level as you can. Just remember to depressurize the system.
