Definitely use a stage 0 (bulk tank) filter on those applications. The more you can do to capture contaminants and remove water at the fuel source, the better you'll help extend life and performance of any stage 1 or stage 2 filters.
Our 3-Way test strips are good for all nitrite-based coolants...older technologies so it's more consistent across different brands of product. When you get into OAT coolants though, those test strips do tend to be brand specific because the additive chemistries are more varied.
Yeah...but good luck with that in a real-world scenario. I can vouch for what I've seen us do...these guys look like a fly-by night operation selling cheap stuff out of Asia. Just my opinion though.
I mean what are you really saving by using them over a genuine product? Seems like a high risk...
It's a huge problem for legit filter manufacturing companies. We see millions of dollars of counterfeit product coming in from Asia every year and it's getting worse with Amazon now.
And regarding volumes, that single part number that has been getting ripped off is easily a top 10 part for...
If you want to get all of that rust/corrosion out the system, try this stuff: https://cms.fleetguard.com/en_NA/literature/restoretmrestoretm-plus-heavy-duty-coolant-cleaners/lt36625
I was referring to true shelf life. Useful service life is going to depend on the type and technology. We have million mile, life-of-the-engine coolants for example.
I actually have a decent amount of information on both of those filters since they're top runners in our business. I've got SEM (scanning electron microscope) images of the media layers for both of those. What do you want to see/know? Are you interested in running the LF14000NN/LF14001NN on a...
Not sure how pricing compares, but we have some small fuel processors as well if you wanted to look; the FH235 appears to be in the size range of what you want: https://cms.fleetguard.com/en_NA/literature/complete-portfolio-fleetguardr-fuel-processors/lt36579-new
