Bought 2005 tundra trd sr5 several years ago and have found this sight very help full many times with repair questions. My question has been asked many times and is allways avoided by everyone . My secondary air pump has just started to make noise and the popular reply is to bypass the system. I have the 4.6 v8 hand do not want to do bypass. My truck has just under 150000 miles and has had a very pampered life. It is all stock and in very good condition for the year. My question is has any one used the napa replacement pump with any luck. It is made by doorman

 

Any one have the part #s fore the 2 hoses that connect to the oil filter cooler. That is the round part directly behind the oil filter. Not having any luck on line finding them.

 

I got mine from yotashop, but they're for an '02.

Thank you Mr. Bee

 

Couple of reasons I chose to bypass.
#1 -The Cost . . . . 'estimates' upwards of $3K to remove/ replace the entire system.
#2 - It's the same 'S' . . . from my understanding Toyota hasn't 'fixed' any of the issues with the system itself. So I'd be replacing old parts that failed early, with a set of identical new parts that could fail just as early as well.

Some first gen owners go much longer than others with their SAS system . . . mine lasted approx. 60K miles, others much longer.
Knowing my luck, it would fail the next week after installing a whole new system . . . $300 was more appealing than $3K

YMMV

 

I recommend keeping the system and not bypassing. Simply because it seems to be 60/40 on success/fail for these trucks using any of the bypasses on the market, including Hewitt's (seems more folks have trouble with Hewitt's newer generation, but I think a lot of the issues are install failures FWIW).

That said, this is the wisdom/experience I would impart on you @georgem306 --- There are two companies who I'll typically trust for aftermarket replacement parts. Dorman is one. Standard Motor Products (SMP) is another. Delco

Why?

Take one of my previous trucks as an example, a '98 GM 1500 (GMT400). When GM stopped making the intermediate shaft, which is problematic in both the GMT400 and GMT800, I contacted corporate and asked them what the hell I'm supposed to do. They basically said, "Buy the Dorman replacement part, it's identical". Beyond that, the fuel pump/squid in their Vortec engine? Made by SMP.

I know this isn't isolated to GM products. Those two companies specifically make various parts for various OEMs. And they don't seem to be like Delco, who can be a mixed bag when it comes to parts and part quality. I've met a lot of people who equate Dorman with cheap "HELP!" quick fix products. I get it. But they also make parts that are worthwhile.

I'll just say two other things: One, someone on here suggested there's a brand out there (that's not Toyota/Denso) that made the SAI pump for Toyota domestically, and is cheaper than OEM, I distinctly remember the post and I think I even asked for more details but can't recall if we got them. Two, while I personally recommend going OEM on any job that requires the amount of time/effort of replacing anything living under the manifold, I understand OEM is spendy, but I'd also say ... it lasted how many years now? While I see the draw of buying a part at half the cost, what's saving $300 if the non-OEM part fails 3-5 years from now and you're doing it all over again? At that point, you're in it for the same amount of $$$, but twice the work.

 

What causes the failure? Bushings? Corrosion? Plastic fatigue?
