Review on OKAY MOTOR Secondary Air Injection Pump for 2007-2013 Toyota Tundra Land Cruiser Sequoia LX570 by Brad Ward

I got an emissions code on my tundra - it worked fine for a while then went into crawl mode. Ouch! I needed 2 of these air pumps and a new design snorkel tub to prevent a recurrence. You must prepare the patient by removing (partially) the passenger wheel and fender trim to access the dead parts. The old pumps came off easily, but the new parts fit well - just don't remove any parts other than what you need - keep it simple. Opening the old pumps reveals that one of them was filled with water, so the new snorkel design prevents water from entering the system. Buy a new snorkel tube from Toyota! And don't buy the electronic bypass junk that some advertise online. This easily solved my code and crawl mode. Some may need to replace another part of the valve at the top behind the intake manifold - I haven't done it yet.
