TH350 modulator line

How did everyone run this line? Did you run it out of hard line or just rubber line? thanks

I ran rubber vacumn line down to mine when I had it. I used plastic zip ties to hold it from anything that would melt it, exhaust and such. Never had any problems the 10 years I ran that setup.

Re: TH350 modulator line

just use some brake line from the auto parts stores and flare the ends, it bends easily and can't melt. use rubber line for the 3 inches on either end with some zip ties or hose clamps to keep it connected.

Hardline off a junkyard car up to about the back of the intake manifold and then rubber vacuum hose from there.
