Im in the process of trying to do this. I have 2 fittings that fit into the turbo with 3/8s barbs. The problem I am having is finding a rubber hose that will securly fit the 3/8s barbs while on the other end connect to the hard coolant lines. So I was just wondering what you folks did to connect the gap together? For me there is such a big diference in the two sizes.

I simply went to Ace Hardware and got the following:

2 x 3/8 barb with 5/8 npt thread
2 x 5/8 bard with 5/8 npt thread
2 x 5/8 npt thread female to female joiner

Then simply screw one 3/8 barb into one side of the female, and one 5/8 in the other side... and do the same with the other one... and there you have it.

3/8 barb ---5/8 npt---5/8 npt--- 5/8 barb

Enjoy. :thumbsup

i would think they would make a barb fitting that had 3/8 on end and 5/8 on the other..??
