    08 tundra with more air pump problems. I need emmissions test in a couple of weeks and I will fail. Light on, limp mode. I want to fix this properly and be done with it. Its been an issue off and on for YEARS.

    Truck has very low miles and I'm the only owner. Toyota tried to fix it once so no more extended warranty. I have complained to everyone. They refuse. My 08 is a 4.7 truck.

    The wiring connector that goes to the pump under the manifold only has a single heavy gauge wire at the connector. My pump in the wheel well has 2 wires. Does the pump under the manifold just ground to the block or something. I'm trying to figure out how to relocate my pumps but info on 08 4.7's is slim. I want to get parts ready but can't see the pump under there. I now have no choice but to do this myself and I have no urge to leave the air pumps where they are. Its been ridiculous and expensive. The 07 has a 2 wire connector for manifold pump. My 2008 is different with only one wire.

    Can anybody help me PLEASE. Picture of my setup someplace??? Any information??? Thank you !

    I forgot to add, that my thinking is if I want to move the pump from under the manifold why do I even need to pull the manifold to get at it. If I can figure out the wiring, the plumbing is obvious. Just use longer wires and hoses and bypass the existing and put the new pumps somewhere else like behind the air filter. Is my thinking flawed? Thanks again.

    Thanks but I'm old, cautious, and have no interest in doing anything that can possibly get me into trouble. I just want to put the new pumps where I can monitor there condition easily. I need hip replacement and back surgery and I sadly can't stand the pain of doing jobs like this anymore. I need it done and out of my head (and stomach). Don't ever get old. There is nothing good about it. I am not against the bypass, I think it's great that people have that option. Kudos to the guys that figured it out. Can anyone help me?
