I did a little hunting and found a number for a Wells Manufacturing in California. their ph number is (818) 767 0955.

Is this the same wells that makes the electrical replacement parts? As in the MAF that everyone goes crazy over?

Reason is I want to buy a 2 bar MAP sensor and they may have one #SU129 but Autozone couldnt tell me if it was a 2 bar or not. It sure is cheaper than going through GM who wants $78 compared to the wells one which is $29.

Sorry for the slow reply. Wells Manufacturing can be reached at (920) 922-5900. For a more technical question such as that, the marketing department may not be helpful. You may have to ask for an application engineer (Mr. Garrow).

Did it take Vader 4 years to reply to this thread? Better late than never

ROFL!

I didn't moderate this forum back then. I try to get everyone a response, so no one is left out. I'll generally wait for others to reply, so everyone participates (and I can learn something). If there are no replies after several days, I try to respond just so the poster does not get discouraged. Sometimes that reply is a redirect to a more appropriate forum, sometimes it gets direct input from me, and sometimes the thread gets deleted if it doesn't belong.

I spent a couple days going over old posts with no replies, and this is the result. There are about 1,500 fewer posts in this forum today than there were three days ago. All of those that were deleted were read by me to be sure that no useful content was being deleted. I saved several hundred as well. I started from the beginning archives from 2000, and stopped reviewing posts newer than one year, and may go back to it later. Does the board load a little faster for you now? The search certainly works a little better. I still need to clean up some of the "stickies" I created so the content was preserved.

Since this particular question arises on occasion, I thought a reply was prudent.

Yes, it's pretty odd to see an old post with a fresh reply.

Believe me...I am not being critical...it is just kind of funny.

I suppose it is kind of analagous to how rock stars get around to answering volumes of fan mail. Right?

Ah Vader, the trials and tribulations of celebrity.... Thanks keep up the good work!

Ands the resultant answer to the original questiuon was...?

As of late February of this year (2005), the SU145 replacement MAF was still an active item, in inventory, and according to the Wells marketing department, available through any CarQuest parts store. They may have to order it, but they are an authorized distribution chain, along with several others like Blain's Supply and Original Equipment, Inc..

The SU129 is also still available, even at AutoZone for about $50.


88TPI,

Yes, I was hoping someone would see the humor in it. I also posted a reply since the question arises periodically (as you can see), and since I had recently spoken with Wells, I thought I'd update the situation. There are still a lot of MAF cars out there.

Just an update on the Wells Su-145 MAF. I tried ordering it through World discount Auto Parts and was advised that I would receive a Bosch in place of the 145. The reason the person offered this information is others have ordered the same part with the same disappointing discovery of finding the bosch in a wells box. To that I said "thanks for the heads up as this is also not what I want".

Then I called the (920) 922-5900 and spoke with Jim who verified this sad truth. He had to verify it with an engineer before calling me back.

When leaving my call back number to Jim I mentioned that he might get a Medical Systems recording ( My work) And that brought up a friendly conversation as the Wells plant is not far from our HQ.

From this conversation he also mentioned that Mr. Garrow is no longer working there.

Here's what I heard back when I tried to get one, and the follow on responses:

Wells MAF

chickenhawk

Yep, already read that thread. Not willing to take a chance on a microtech part.

However I would purchase a Wells if available. Thus this is where my search has ended.

Additionally, I to have grown tired of waiting for a response from Car Quest. ( This is what had prompted me to call World Parts first and then Wells directly)

If anyone has any info to the contrary regarding the availability of the SU-145 ( Film MAF only, not a Bosch wire MAF in a Wells box using the SU-145#) or a Film MAF by Wells that has replaced the SU-145 then I'm all ears, otherwise I'll pass.

Anyone with solid info regarding the SU-145 other than what I have found in my previous posts? I see that the granatelli adjustable MAF is still available.

Not that I want one, but some have said its a modified Wells SU-145 and from what I've seen it does look the same internally from the pics some have posted.

If that is the case, I am just wondering who is providing them?

Unless granatelli has bought the last stash of the SU-145s and will soon disappear.

Or someone else is making them for granatelli?

I dunno Just looking to replace my screenless bosch and my first choice would be a Wells.

Regarding the granatelli, I did a search after posting and I may have found my answer. Well, maybe....Here is the link to the microtech MAF.

Now look at the Wells Vader posted in this thread.

https://www.thirdgen.org/techbb2/sho...adjustable+MAF

It looks like a microtech to me, which looks like a Wells SU-145

I'm running the Micro-Tech unit in my 87. It works great!!!!!!! If I get a chance tomorrow I'll post pictures of my old Bosch and the Micro-Tech unit side by side so you can see the difference.

cdartz

Ok here is the side by side shot of my Micro-Tech MAF and my old Bosch MAF. You can clearly see the design changes.

chickenhawk

Thanks CDARTZ!!! I appreciate your help!!!
Still curious to know if this is the same as a Wells but really doesnt matter at this point since you have indicated that this replacement works great and is still a film MAF which is what I want without having to spend 300+ on an adjustable granatelli.

Looks just like a Wells from Vaders post and if it performs than thats good enough for me.

Additionally, there is something about having an adjustment on the MAF (granatelli) that doesnt set well with me. For one I would rather make changes on a prom than at the MAF.
Secondly, it just seems to me that this would be another component that would add potential for failure.( the variable cap or pot that they use to make it adjustable, I dont know exactly how they adjust it)

Also interesting to know, regarding the Microtech, that advance auto parts will sell it if you have the correct part# but they do not offer it or even list it as a replacement for the original. Had the guy look it up and he said " well this is not what I show for your car".

Also checked for myself on thier site with the same results.

But, as clearly stated at the Microtech site, this is what I need.

Anyway, Im convinced!!! Microtech it is!!

Thanks again.

cdartz

I don't know what Advance you went to, but it sounds like the guy didn't know what he was doing. I'm a manager for Advance, and this is clearly the replacement listed in our electronic parts catalogue. In fact it's not even an order item at my store. We have it on the shelf. That may not be the case in most stores however as my store is a hub store we stock more than most.

chickenhawk

Yeah, dont know if your in store parts inventory\look-up is the same, doubt it is, but here is what I found by application on the web site. The store I go to is a new one in Joliet. They said they would have to order it. Also, if you search with the Microtech# it returns with a description but doesnt give an application.

My guess is, if they corrected this, you would sell more, at least from the web, given the results by application isnt also limited through the store inventory search as well.

Just a thought...

Thanks again.

Just for reference:

And for keeping the information current, the MicroTech 49-1018A is a clone of the Wells SU-145, right down to the mold marks in the new (not recycled), larger case. I just recently acquired one for a retrofit project, and the sensing board looks identical to the Wells SU-145 mounted on my T/A. $168 at Parts America, and other fine retailers.

So is the MicroTech 49-1018A larger that the stock MAF sensor.If so, how much larger.

Vader,
Wondering what the deal is with the microtech 1018A unit. I am shopping for a replacment MAF for my 85 tpi (no it wasnt the MAS thank god), and this is listed as a replacement. This obviously has to be an error due to the digital signal of my 85 MAF vs. the analog signal of 86+ units. The appications are listed as 85-89 on the microtech web page as well. I guess I am going to stay away from it, but are there any other options for a thick film sensor for 1985?

***Really confused now. After searching a little i found this post: https://www.thirdgen.org/forums/tpi/...light=1985+maf

According to this, 1985 cars also came with the analog sensor, the 5 wire. My sensor is a 5 wire, but i also have the 870 ecm and the MAS module. So whats the deal? Will an analog swap in?***

There is a flag in the ECU to use digital or analog MAF. If you don't burn your own chips I don't think you can use an analog maf on the later car

Well just put in an 86+ MAF (analog) unit in my 85 (Supposedly digital) because no one carries the 85 MAF's and I didnt want to order one. So I figured I would just answer my own question. Turns out it works fine, no problems, no stumbles, stalling, check engine lights etc...I couldnt say for sure how it was doing because I dont have a scanner or tuning programs, but it runs just like it did before it went out, with no driveability issues yet.
