Do you think the fuel pump lies in the bottom of the tank?![]()
Most modern FI engines do I believe.
In the case of the 05-06 TJ, The answer to both of you might be "yes, but..."
The pump is at least in the bottom half, but I haven't had this module apart to know exactly how low.
That being said, it looks as though it's always submerged regardless of the tank level, as it sits in a bucket of sorts that gets filled by the regulator return dump tube, constantly replenishing the supply of cool fuel to the pump "cooling bucket".
So yes it needs fuel to keep cool, and yes it's in the bottom of the tank, but the design is such that it has that regardless of the level in the tank.
If I understand it correctly it's actually kinda clever.
