Here's where I found to buy Norma clamps. Nobody has prices so I assume they only sell in large bulk.

I think Firefox just made my day

Fastenal sells oetiker clamps in stainless in qty one at about $ 0.50 each.

Weird, I found Red House Supply in 10/2021 and the site was functional. Google still returns results when searching for "red house supply", but the links don't work. Maybe a temporary outage, maybe permanent. They had lots of good hose clamps.

I've been making note of the Norma part numbers on clamps that I work with. From my notes:
Stainless classifications, per Red House Supply:
W2 - galvanized screw, 430 band
W3 - 430 screw, 430 band
W4 - 304 screw, 304 band
W5 - 316 screw, 316 band
Specs - https://powered-by.qbank-mediaportal.se ... eet-en.pdf

The link to the spec sheet is also broken now.

This appears to be my problem as well. Oil drenched engine front and half the oil pan. (Leaked fluid is green)
Pump has been recently replaced. Reservoir and supply hose look suspect.i washed it off with Super Clean. I'll see how it does tomorrow.

Dixon Wave Seal clamps would be a good choice as well. A bit spendy though.

On two different 2000 V70s, I noticed that newly installed reservoirs swelled quite quickly after install. The system is pressurized and that causes the expansion. It's a common problem that expansion for 10+ years causes leaking at the horizontal seam. I'm saying that swelling is common immediately thus not an indication of failure in itself. As you did, it's best to clean the tank and check for leaking at the seam.

I've also experienced leaking at worm gear clamps because I failed to tighten them enough. Fluid drips down on to the seam making it look like the seam is leaking. Be sure to tighten the clamps firmly.

Did the new hose and clamp(s) fix the leak?

I recently had to remove the power steering pump to access the alternator. Now that everything is put back together, my power steering pump has that same looking leak. I can see ATF drip-drip-drip on the oil filter after driving. I had to top off the fluid last week.

I cleaned the area around the hose clamp and hard line fitting and the leak doesn't seem to be coming from those two connections. Is there anywhere else on the pump where the fluid can leak?

Oh man. Wow. I honestly can’t remember what I did. I put a new used worm gear clamp on it but didn’t change the hose. I’ve not had any PS leaks so that must have done the trick. Sorry it’s just been forever.
