Fuel Press. Reg. Vacuum Line Question
Where does the vacuum line that runs from the FPR and plenum (they join into one line) run too up front? The line is so long that it runs about where the MAF is and I can't figure it out. Thanks. :cheers:

There are two fittings on the right rear of the plenum; one of these goes to the FPR.
The line from up front should go from the EGR Solenoid to the EGR Valve under the the plenum.

Since you aren't using the EGR you have a spare vacuum fitting.
Get a rubber cap from AutoZone, remove that unused vacuum line from the fitting and cap the fitting.

Re: Fuel Press. Reg. Vacuum Line Question (dtorc4)
OK, I think I figured it out.
Since I'm not using EGR (the valve opening in the intake has a block-off plate) and I'm not using any AIR stuff (switching valve and diverter valve are not going back on, pump is just being used to take up space), this is what I'm going to do.
I'm taking the T fitting from the switching valve and sticking it on the bottom of the TB. I'm running the vac line from the FPR and the plenum to the TB T fitting going to the pass side. I'm hooking up the other side to the vac control valve L fitting (coming right off the end of the valve). I'm running the vac line from the canister to the small fitting sticking out of the side of the the vac control valve.
Will this work???? :confused:

Ok, after further inspection, I'm going to switch the vac lines on the vac control valve. The L fitting on the end of the valve will be connected to the line running to the can, and the small fitting sticking out of the side of the valve will be run to the TB. Anybody else have any suggestions? I just want to make sure this thing is correct. :cheers:
