CAC boot not able to tighten

I replaced the upper fuel filter today. I removed the following CAC boot part 4C24-6C646-BC: to make the job easier.


It may be the original part that came with the van in 2004. I pulled it off and cleaned with hot soapy water. I cleaned the tubes with brake cleaner. As a last resort, I used hair spray to get the clamps to not slip. Out of luck. My 15-minute fuel filter replacement is going on 4 hours.

Every black CAC boot is slipping. I replaced all the blue CAC boots last year.

Any ideas on tightening these beasts or do I order new ones?

I found a new old stock hose on eBay for $20Home 2004 Ford E-350 Club Wagon Intercooler 4C2Z-6C640-CA
Intake Hose - Ford (4C2Z-6C640-CA).


Amazon sells GATES 26217 hoses that include new clamps.

Hard to tell from your photo but if the clamp's threads are in bad shape it might feel tight but it's not because it is binding. Check that the threads are clean.

I will replace the boat and clamps. I don’t want anything happening on my next 10,000 mile trip. The part number does not come up in any automotive online part stores or four dealerships. Or less and $50 I can replace the clamps and that hose.

I sanded the aluminum tubes to make the surface rough. I had my 18-year-old son help align the boots while I held everything tight. The Milwaukee cordless wrench vibrated too much causing the tubes to slip off. We used a GearWrench socket driver to make everything tight.

The boots are tight.

Use Dawn dishwashing soap to clean everything including the boots. Get new clamps if yours are old. Hairspray works, I like TreSemme black can extra hold.

I ordered the Mishimoto T clamps. I found a new boot on eBay for $20 including shipping. We have Dawn soap.

Thanks!

I have a buzz cut. I don't believe TreSemme will work on my short hair. LOL!

My wife has some hair spray.

I have a full set of Motorcraft boots I would have sold you for $50. I replaced with RiffRaff silicone boots and clamps. The turbo boot is new.

Keep in mind he has a Van front end. I don't know if the boots are the same or not. Does anyone know?

they were installed when I bought the truck about 3 years ago with 150k. I blew a hole in the turbo boot and replaced it with a new Motorcraft boot. I have wuite a few 6.0 parts in the classifieds too.

The van has different boots. Diesel Tech Ron posted a video about replacing boots and said they can be interchanged if and only if needed in a pinch. I suspect the boot that I am replacing is from an F-series rather than E-series. It's not long enough.
