Thanks, that's the 1/2" one "Brass" Do ya have one of the 1x1/2?

Just changed my Santa want list to the dfusser coolant filter. Hope Im doing the right thing. Does anyone have any experience with the dfusser filter?

Thanks, Rob

Nope, but I do have the dieselsite filter and have had not a single lick of trouble with it.

U would say it's hard to mess up a filter kit .. but then again lol

you will more than likley just get your replacment filters from napa anyway

Bob,

I did not mean to imply that I don't like the Dieselsite filter kit. I do and would buy one again. The kit was well designed and packaged. I really liked the billet filter housing, looks good and professionally done. I didn't prefer the aluminum tee, however. I too have an engineering background and felt that the thousands of heat cycles and any side loading from the hose routing could affect the reliability of the part. Thanks.

I agree, I will be getting a fitting from ace.

Thanks for the info guys I think I'll buy the pex t. I just got the kit in today and haven't had a chance to check it out yet. No reason to take a chance when a cure is a couple of bucks.

Hi All,

New guy here. I found this forum a little while ago and decided to finally register.
First I would like to thank Bob from Dieselite for putting this kit together. I installed one this year and it looks good. However, being in central Maine and going into the winter with this pressed aluminum fitting, does not make me feel secure.

I will be seeing many nights below 0, and some 20 below or more. Between the continuous thermal expansion and the stiffness of the hoses at those temperatures, I don’t feel that a 2 piece, press fit, aluminum tee is the best choice. It’s a risk easily avoided and not worth taking. Interference (Press) fit parts are subject to manufacturing variables. Unless each part is mechanically tested, they are only visually inspected.

I just swapped out the tee from Dieselsite with a brass PEX 1x1x1/2. It fit perfectly. I was able to find the same brass tee on line for less than $3 each, my cost. I imagine in bulk they can be had cheaper. Just out of curiosity, I held the Dieselsite fitting in my hand, grabbed the small barb with a pair of pliers and twisted. It rotated and fell off very easily. Much easier than I expected. If Dieselsite continues to make their own part, it should be threaded and loc-tightened in my opinion.

I would also like to thank the original poster for bringing this to our attention. He put in a lot of effort and time documenting this for us. I don’t agree with Dieselsite’s position that “you chuckle that someone starts a post with "Warning". The original poster was not derogatory toward Deiselsite at all. He was just stating the facts along with a helpful fix. Some of us are comfortable with the original part, while others like me prefer to use a one piece fitting and appreciate the information.

Dieselsites assertion that “However, they are affected by too much "manhandling" when guys get over generous with the torque applied to the clamps and twist the unit apart.” Tells me there is a known issue with this part.

I never worried about breaking a metal hose barb while tightening on a rubber hose with a hose clamp. I might worry about crushing the hose or maybe stripping the clamp but never worrying about the fitting falling apart. I have to think that the extreme temperature changes and physical stress on the hoses at 20 below put more strain on the fitting than I could do by installing it.

Thanks again to all on this board. Together we can all have a better running truck.

To those who are using the 1x1x1/2 pex tee, just how tight of a fit are the hoses? I think I might pick one up tomorrow.

Nothing to it. Goes right on. If you have the original tee, check to see how easy it comes apart. I'm curious if I got a weak one.

Thanks

I will test the strength of the pressed tee and post the results as soon as I do it.

Nothing that a little lubricant and a hair dryer or heat gun won't take care of

Care to post a link? I didn't have much luck finding that item, including McMaster which has just about everything. I don't think I will find it locally either, because PEX is not yet approved in the local building code.

I found mine in Lowes. It was in the plumbing section. Home Deopt only had 3/4x3/4x1/2.
You want 1x1x1/2. I put it in while the engine was warm. It went right on. You just need to open the clamps up. I tried the same thing Captain Bill did. It came apart without much effort.
