I may have missed it, but what are the specs for the heater hose barb?

The specs are you take the spacer and heater hose to ACE Hardware and find one that fits.

Just kidding. It's 3/8" NPT to 5/8" Hose Barb.

Thanks.

I am installing the Begi reroute kit as soon as it shows up in the mail. All of the pictures from this write up are gone and replaced with a "Bandwidth Exceeded" message. Is there any way to view the pictures or the write up as originally posted?

Use revlimiter's blog write up, it's very helpful.
