Can someone help me out. I have a dash light on that i'm guessing means i need to drain the fuel water separator. I think i found where to do it and opened the drain plug but only a little bit of fuel came out so i think i'm doing something wrong. This is the first cruiser i have worked on and i don't have any manuals to go off of. So any help would be great.

It's kinda interesting cuz it's a middle eastern cruiser so the data plates are in arabic, which i do not know. The model is a GX.R it's a 2009 and i think it's a 4.5 liter turbo diesel. Thanks. I'll go see if i can get more info off of it. went and looked it says the engine is a 1vd-ftv

D-4D is just a market classification for Diesel 4-cylinder Low-emissions engines. Otherwise, it depends on the model of motor.
 
i can't really do the whole picture thing cuz it's a military truck and you know how they are about pictures. i was just hopin someone on here had drained one before and could give me some tips. i'm sure a could get it to drain i just don't see a priming pump on it anywhere like my duramax has. so i'm mostly worried about getting air in the system and not being able to get it to start.
 
Why not just change the filter, it's simple to do ( Not sure on the exact model ) but remove two pipes and take the wire off, then remove filter and fit new one, you can even fill the new one with diesel before fitting, then you wont have problems with air in the system.
