Hi.. I have a few questions:

(88 mustang gt.... ELIMINATED AC)

Starting with what I did... I replaced the single manifold source vacuum line that runs from the back of the manifold up to the vacuum distribution block...

Then I replaced the Brake vacuum line that comes from the vacuum distribution block.

I ran a line from the a/c spot on the vacuum distribution block to the 1 to 2 splitter on the firewall (just unplugged the two vacuum lines going into the firewall for now.... From there 1 line goes directly to the tad solenoid and another goes to the tab solenoid... in one of those vacuum lines there is another splitter. That is split to the a/c reservoir canister...

Can I just cap that off??? And go direct... I am assuming so..

Because now I don't have a spot to run to the egr vac regulator I just ran a new line that runs from the capped off spot on the vacuum distribution block it.

I know one of the lines that goes through the passenger firewall is the evaporator gasket... and I'm not sure what the other passenger firewall line is for.. Hoping it is a/c related so I don't have to worry about it... Anyone know??

I would like to be able to cap off that a/c reservoir canister.. that would likely close the gap on any other possible leaks..

The only other line is the cruise control vacuum line which I haven't touched..

Because everything I listed above is through the vacuum distribution block on the driverside firewall.. I think I should be ok for leaks because it is isolated on its on manifold vacuum line..

Should I worry about the purge solenoid, vapor canister, and fuel tank.

I also don't know anything about what the MAP and FRP lines do.. I still have speed density!

Sorry this was so long any ideas would be great!!
