I am working off the simplified sequential vacuum diagram. Where does the hose go that comes off the LIM facing toward the rear of the car? Normally it would go to a pressure regulator solenoid......then another hose comes out and goes to the fuel pressure regulator.......but that solenoid is not used in the simplified sequential setup!! So do I hook that hose directly to the fuel pressure regulator and bypass the solenoid or what???

Second, after doing some searching I read that the fuel hose closest to the firewall is return line....and the middle is evap purge, and the one toward the front is incoming pressure. But if you look at the line, the one closest to the firewall is just emission hose.....not braided EFI fuel line! now the middle and front line are EFI braided lines!! Whats the deal here???

Third, does anyone have any issues using the simplified setup? Just wanna make sure before everything goes back together!!


Last, I am blocking off everything but the idle speed controller. Do the 2 inlet and outlet AWS holes have to be blocked? These are the one on the rear of the LIM and pass. side of the LIM. I didnt know if it was actually vented to the LIM ports or just a passage for the AWS system and can be left open?

Thanks!!!

Dont know about the simplified solenoids, but the fuel line with the grey writing goes on the mount closest to the firewall, the line with the blue writing goes on the highest one and the other line goes on the last one:

 

Anone else have any insight??

 

That hose goes to the front nipple (connector side) on the pressure regulator solenoid. It is not shown in the simp. diagram, but it is used. The other hose attaches from the top nipple on the solenoid and is ran to the FPR itself. See the full vacuum hose diagram for a reference on how to plumb it.

As for the AWS hose. It is recommended to block it off. If you bought a block-off-plate kit, it has the neccesary pieces to block off all of the emissions stuff. There is one extra B.O.P. that is not used, though. It is for the ISC.

 

Well, thats nice to know now after I have everything installed!! Oh well!! But now that you mention it, are there any other solenoids that need to be used that arent on the simplified diagram?? I only hooked up what it said to!!
BUMP!!

 

Nope, that is the only one. That diagram has been around for a while, and I think the guy that did it didn't show anything for the FPR because he had a custom setup. Some people say you don't have to use that solenoid, some do. That solenoid is used for "hot-starting". It raises the line pressure in the fuel rail when the fuel is above a certain temperature to prevent vapor-lock. I have read of some people eliminating that solenoid and not having any problems. I chose to keep it just so I don't have to wonder.

cool, thanks joe. I got it hooked up, but it took some patience!! Hopefully all my parts will be in this week and she'll be on the road by next weekend!!
