There are two vacuum ports on the passenger side rear of the tpi plenum, one for the MAP sensor and one for the fuel pressure regulator hoses. Does it matter which hose plugs into which port? I have found conflicting information on the factory routing and the supplied vacuum diagrams don't show much.

Thanks

 

If the hoses fit both nipples it technically doesn't matter. They're both supplied by the same source.
The MAP sensor should have a boot that really only can fit onto one of the nipples due to how it's been formed.
You should have 3 nipples back there.
MAP
FPR
HVAC/Cruise Control

 

Got it. The FPR and the MAP are the same size ports. The third (furthest forward) is larger and not as offset.

Thanks
