ok, so I'm looking at my vacuum lines as I put them back together, I can only see 2 pipes coming out of back of upper intake, a site says this it 95-97 explorer intake, a 97.5 has a different setup. with only one thin pipe in back I put a 3 way spitter on it and ive got egr, heater vent lines, and fuel pressure regulator on that together. I read you should have fpr by itself in case diaphragm rips fuel wont go into other places? so do I have it right or should they be hooked up different. I'm wondering if fpr needs its own to work right?

 

Yes, FPR often has dedicated vacuum port but long shot that diaphragm would ever leak, and if it did fuel would be sucked into intake by the vacuum.
And you would notice it right away with engine stumbling and hard starting, once repaired intake vacuum would clean out any effected hoses.

 

Ok I get it, I just cant find any other vac ports to hook any lines to. I trying to look at other areas that could be causing the problem.
