I cleaned my oil vapor separator (OVS) and all corresponding hoses to check things out on my '90 Quad... now I can't for the life of me put the hose clamps on. I was able to pluck them off easily with a screw driver, but won't go back on as easily (with my luck). Is there an easy way to clamp these back on or a special tool needed?? I've tried everything from pliers to my bare hands. What are these special clamps called? (For future reference).

Just go to the auto part store and get some new hose clamps (worm style with screw). They'll work fine to replace the original ones.

Yes, I actually have some of those laying around and contemplated using those but just wanted to keep things looking original

You can get specialised "Click -R" pliers to do this, but I use my carpenter's pincers to re fasten these clips. They are actually superior to the screw / jubilee type hose clamp as they always apply the correct pressure without damaging the hose.

You may also be able to use a pair of side cutting pliers to fasten these.

Had same problem, as I am sure many others have. Never could get back on. But recently saw similar type "pinch clamps" and specialized plier ("pinch clamp tool") to apply them sold at Lowes for around $12.

This kit has what looks just like the carpenters pincers referred to by Mark Cooper.
I used the same type of pincer on the hoses attached to the intank pump. Fiddly but it worked.

Thank you all for the responses. I have cutting pliers but would think they might damage the clip? These carpenter plicers I don't have, should pick one up for future use. Meanwhile I just used the worm style clamps since I had some on hand with the appropriate size. They look fine and believe to be adequate for a few OVS hoses. I did save the originals.

I have the same clips on my 1997 Fiat. I replace them as required with the worm screw type. Easier to fix with my on-board tool kit should I have a breakdown.

Is it possible that the difficulties you are having re-installing those clamps is due to a change in the hose dimension? That is, might the hose swell from exposure to oil and heat? So while it might require only 10# of force to snap the clamp over a new hose (I just made up that number), it could take 20# to fit it over an old hose?

Just a theory - I have no direct experience - I just use cheap, simple worm gear clamps.

Look at the other hose clamp ijn his picture......
I did, and I've already subtracted 10 concours points :D

Seriously, worm clamps are fine, just don't over tighten them and damage the hose. That's a vacuum line and isn't holding pressure so it only needs to be reasonably snug to prevent leaks.
