Just finished installing my Racetronix Walbro 340 kit. I must say it is a very thorough and complete kit with the exception of the 4 pin connector being wired backwards. The red wire from the pump needs to go to the gray wire on the connector, and purple from the sender to purple out of the tank. The purple wire is the pin closest to the metal locking connector, I verified this with a continuity tester. If you follow the instuctions, you will wire it BACKWARDS. I paid a little more for this kit, because I wanted the best I could get. I see there is a post over a year old describing this very problem, and yet the instructions are still wrong. What say you Mr. Racetronix?
