Is there like a program or something that capitalizes the first letter of each word? I've seen this effect here and there on the forum. It's kind of distracting.

To attempt to answer your question, I'm going to have to say the only vacuum tube or hose that connects to a CPU would have to be a MAP sensor, which stock 1st gen ECUs don't have. Are you sure you're not talking about a brake booster hose, or something?

If you change to an aftermarket carb, you can ditch all the hoses.

First go to www.mazspeed.com and follow the de-emission tutorial. Then hook your carb up and get rid of whatevers may be left over that you don't need.(shouldn't be anything)
