Hey everyone, I'm Paul and I'm new to this forum. I have a 1985 300zxt with some problems. First, the A/C only blows hot air but i have already done some research and i discovered it's a vacuum line problem. So i replaced all the vacuum lines that deal with the A/C EXCEPT the one line that goes through the firewall on the passenger side. The line broke halfway while i was trying to pull it out of the firewall with the new hose attached to it. So now with the old hose out, i tried feeding the new hose in through the firewall from the engine bay and i can't seem to get it to drop down to where i can reach it from the passenger side. Any ideas? Also my fuel gauge kind of works. When it has a full tank it, it reads full. But right about when 3 gallons are used up from full, the gauge goes all the way down to empty. Can this be the fuel sender? If so how do I fix this problem?

Thanks for all your help

For the vacuum line, use a coat hanger or similar.

For the fuel gauge, replace the fuel level sending unit. You get to it in the trunk.

Cool, thanks for the help. I'll go do that.

Coat hanger failed, so i'm going to see if i can find another entry way.

then the easiest way is to pull the dash.
