2 things I can think of that cause the extra fuel!
1: if it revs quicker it might be using a litte extra that way.
2: if it keeps it to cool then it might (even if it's only for a few seconds) it might possibly be in warm up mode.
Getting back to the thermostat and where you have possitioned the temp guage for the new pump!
As mentioned before, it might be wise to take the temperature closer to the heads for obviouse reasons.
I believe the extra flow provided from removing the thermostat is good and bad, cools it down quicker, this can also do damage as motors are designed to run at a constant temp not a fluctuating temp causing warping and other head aches,,,
I would try and find a lower temp thermostat so that it still has the proper warm up mode and possibly a more constant flow. Maybe even drill a larger hole in the thermostat as per gojeep's site..
I am not in anyway saying your mod is a bad one by any means,
but the amount of research I have done lately due to Cherokee overheating problems, I believe more can be done to help the motor and the rest of the system stay at a closer constant temp.
Electric water pumps are a good thing.
There only bad side is, when they stop they stop!!
