Not only to buy from a reliable source, but to also inspect the filter the best you can, no matter where you buy it from. When I changed my oil, the Baldwin oil filter I got was shipped and sold by Amazon. I received it with a big dent in the bottom of it. Knowing how well made and robust that filter is, it got exchanged. I will be going over my filters with a fine-toothed comb from here on out.
This thread also made me go back and look at my order history. I was lucky that I have not purchased anything from Doxa. Needless to say, my days of ordering filters from the Zon are now over.

Can't wait to see the final results here.

I don't have a problem ordering from Amazon if it is sold directly from them. However, my fuel filters will only be sourced locally now.

Just another knock on Amazon. 2 years ago I ordered a replacement magnet for the Allison spin on filter from amazon. It said genuine Allison replacement..,when I got it it was maybe half as think and could barely hold a metal screw compared to the the old / original magnet that would catch the screw from at least an inch away. After that I stopped buying “important” parts from amazon.

Its crazy that you bring this up as I just ordered a new magnet for my dads truck (doesn't service his truck himself and the "transmission shop" didn't transfer the magnet over). I saw alot of bad reviews for the magnet. After some searching though, I found an AC Delco magnet, shipped and sold by Amazon. It came in yesterday and looks just like my factory magnet.

Hey everyone... it's been a busy 2 weeks getting my heap together and attending the 2019 California Hot Rod Reunion.

It's all behind me, and I'll get my ass back on track for the filter shootout.

Thanks for understanding.....

Well, looking up thru the factory plastic wrap, I can see the INNER pleats of the OUTER filter!!



Its a little deceiving, but there is a considerable air gap between the bottom of the media, and the floor of the canister. It is not sealed in any way!



When looking up, the exit fitting is clearly visible. When this filter was made, the entire inner filter assembly was left out. This would allow diesel fuel to enter the filter, flow around the outer filter media completely, come up where the inner filter is missing, and out to the common rail pump COMPLETELY UNFILTERED!

I am not unwrapping the filter, I already emailed Baldwin and will send it off to them for examination, and have ordered a replacement to use in the test.

Surely, I cant be the only one to have received the ONLY filter in this condition.... right?
NOPE, you are not the only one. I just received one exactly like it. Not real anxious to use it, was going to see what your results were on this filter. Seems to resemble the old Parker /Racor before the coalescer !

Purchased from Amazon-Doxa Worldwide
Parker/Racor is silent
Baldwin goes clickety click,
Stamped "Assembled in USA"
You can see straight through the Baldwin, pleats are visible unlike the Parker, a totally different animal !

Last week there appeared to only be one supplier of the Baldwin, Doxa
checking Amazon today, there are several in the same price range including the Amazon Warehouse.

I contacted Parker / Racor. Both Parker / Racor and Baldwin filters are now being produced in the same Baldwin plant in Nebraska. P/R on one side and Baldwin assembly line on the other. It is rumored that somewhere down the road, one of the brands will be eliminated completely and there will only be one brand produced by the company. This is only a rumor within the company and he did not want to be quoted but said it was a real possibility. They are still working out all the details of the merger and the lines are still separate as far as marketing and warranty, so he said don't send your Baldwin to P/R for warranty.

Then I contacted Baldwin, the filters we all bought from Amazon are more than likely genuine Baldwins. BF46062 is a water separator filter, NOT a coalescer, just a filter/water separator filter. These two filters are different and not intended to be the same.

Doxa Worldwide is not a genuine distributor, nor is Amazon but they buy bulk and resell from certified distributors. One of those certified distributors is B-LINE Filters in Odessa Tx, so if you want to be certain that you are not getting a knockoff, order from them. They are also a Parker/Racor distributor.

On micron filtration, the P/R coalescer water separator is a 4 micron absolute, not nominal. P/R is licensed by GM to produce the AC Delco and the P/R is the identical filter ( I think we all knew that). He wasn't inclined to discuss other companies that they produce or manufacture for or supply to (ie, filter parts say to Joe's filter company for assembly).

Baldwin is also a 4 micron absolute filter, but just that, a filter water separator only and he said you can see the pleats when looking up inside the filter, that is normal for this filter. The difference between the BF46062 and the BF9882, the previous filter, is that the current BF46062 is 85-90% efficient removing water and the previous BF9882 is only 25% efficient.

The Parker rep also added that Parker makes two filter assemblies designed for diesel trucks that can be installed between the tank and final filter.

Parker 490R30, about $225, is a fuel water separator filter and head assembly. Replacement filters can be ordered in 2 micron(s), 10micron(T) or 30 micron(P)

Parker 790R30, about $325, is the same only with a 90 gph pump in 12 or 24 volt, as an assembly, with 2,10, or 30 micron filters. This appears to be a very neat compact unit, looks pretty cool.


So...bottom line is that we more than likely have genuine Baldwin water separator filters, they just aren't coalescers like the Parkers..

I don't know much about this, but I would assume having a coalescer in the filter is better?

Coalesce is a type of filter media like cellulose, microglass, hydroglass, etc.
