I have two fittings come out of the firewall which are mounted to a plate. Not that it would look like a stocker under the hood, just wanted heater hoses, not carrying any water. The two fittings at the engine (intake/water pump outlet) are blocked off so no water enters the lines.
One of the older street race, hiding nitrous tricks. We used to run lines inside the heater hoses. One thing I always checked on cars that didn't appear to have nitrous was to touch the heater lines. If they were cold, I had a clue what might actually be on the inside! LOL
Haha, I have that exact same blue Russell push lock hose going up to my carb too. That push lock hose is a booger to assemble if you don't know what you're doing. Boiling water was the key for me (heat the hose), then is was easy to assemble. :)
Yeah, it can be a pain. I lubed the ends with trans fluid and pushed them on. Took a lot of effort. Didn't wear gloves the first time and treated myself to some pretty healthy blisters.
