I took all of the Thanksgiving week off and have had some time to find the fuel leaks. Last week I had some time and replaced the #1 injector pipe. So that puddle of fuel was no longer showing up pooling in a void on top of the intake manifold. I was however still getting fuel dripping in the driveway. So yesterday I really opened her up. I new I needed to remove the pump to replace the oil cooler with stripped threads at the oil pressure sender port. Once I pulled the pump I noticed there was a fuel stain on the side of the block in a location that didn't seem to be caused be the injector leak because I had degreased and power washed the motor after the injector pipe replacement and the block was wet with fuel in this location. I figured I must have a pump leak, which is a known problem with these ZEXEL ME202 pumps, or really any Bosch VE pump clone including the Denso that would have come on these 1KZ-t engines. Fortunately I had a re-seal kit for the Electronic version of the pump which included the shaped rubber O-ring for the cover, however, because it was a seal kit for the electronic version it didn't include the O-ring for throttle shaft. I called up Seattle Injector Co., and they hooked me up with an new O-ring for free.
