If the o-ring on the filter media is not sealing tight against the can then you will have fuel not going through the media. I am assuming that is where the rattle is coming from the media not tight against the can.

What does the rattle from some of the filters have to do with the "new design" we are seeing with the Baldwins? Every filter that has been reported to rattle, has been the old, two stage design.

I have never had a single Racor rattle in 13 years. Someone mentioned above they had a Baldwin rattle but didn't specify if it was red Racor or the new single stage.

My red baldwin that did have the two stage filter rattled and Bobs TP3018 rattles (two stage). Thats just the two I remember off the top of my head. I don't thing anyone with a single filter baldwin has reported that they rattle, but they may rattle too

I suspect that the specs will remain the same, without the secondary polishing element.

That is not true, i would expect that if i contacted an engineer regarding a product that the company that engineer works for manufactures, that he or she would, if they did not know the answer, forward your email to someone who does instead of making things up. I know many engineers, and making things up is not how any of them do business.

Boy, I sure hope so. One of the better things an engineer can do is to find a way to do the exact same thing cheaper or better for the same price. The best thing is to make it better and cheaper. Let us hope that it is something like that.

It is in the nature of an engineer to want to make the best stuff. It is just how most get into the business in the first place. It goes against the grain to make something worse but sometimes the word comes down from the top to cut cost and there is no obvious way to do it without cutting quality. Let us hope that is not the case.

If they are going to change the design so significantly, though, they aught to give it a new part number so we know what we are getting.

I'm trying to figure out how the wif sensor will work with this new design. I don't see what would keep the water from going up to the pump. I'm guessing they feel it will not go through the filter media.

I will try to find a new filter local of the old design and wait a see how the filter shootout goes with these new open design Baldwin's. My
Guess is the bean counters have gone mess up for parker/racor.
Engineer tells me they have only had one design with the 46062 and they tell skeeter that there have been two. I don't doubt skeeter, but it makes me wonder if at this stage in the merger if Baldwin really knows what the heck is going on.
Both are rated @ 4 micron absolute, Racor advertises 99% water removal and Baldwin is 85-90%.
I wonder if those numbers are the difference in 2 stage and single stage design ?
