CPU waterblock / Tubing Issue

[Xaar]

I curently have a Thermaltake Tai-Chi (edit) case which came fitted with watercooling.. I've been running my DFI 939 + opteron 175 on this fine for a long time..

Anyways, I recently decided to switch over to a P5K Deluxe + E4300 (till I get a Q6600). I also decided to change the CPU waterblock to a D-Tek Fuzion in anticipation for the Q6600.
I did a quick google before ordering to ensure I get the correct fitting block as there were 2 types (3/8" & 1/2" Barbs), and according to my google search, the Tai-Chi used 3/8", which I proceeded to order.

I recieved the block a couple of days ago, and there's no way my current tubes will fit it (tubes too thin).

I guess the question is how and what do I need to best fix/fit this? Where can I order it from (pref. all from same supplier)

What size is the existing tubing? I dont think thermaltake supplied the tsunami with watercooling, so likely it was added by the reseller you bought it off, who was that? If you can find out the size, then barbs cost about a pound each from nearly anywhere.

Thanks for the swift reply mate,

I must be tired, as I dont have a Tsunami , I have the Tai-Chi

The tubing is the exact same as in the pics on TT site.

looking at a few reviews, its 3/8" Outside, not inside, which you have barbs for. You may be able to reuse the barbs off the existing block, or 10mm push fit will prob work. However, it might be as easy to change the entire tube to something more standard if the barbs at the other end are removeable also.
