The 3 hoses that I've colored in are causing me a bit of a headache. I can't seem to tell on the car which one is which. I have one that plugs into a vertical nipple that is near the fuel pressure regulator, one that plugs into a nipple that runs parallel to the engine near the fuel pressure regulator, and I have one that seems to come from behind the LIM. Can anyone tell me which one goes with which color on this diagram? TIA!

 

I spent a few hours coloring and double checking to make this... should be accurate.

JR,

When I did the hose job myself, I put these hoses in the correct spots like in the diagram.

When i had the motor done at KD, Dave routed the vac line from the FPR to the origin of the blue hose closest to the FPR.
So on the solinoid, there was only one hose. Its works great today...

Hope this makes sense....

 

OK, I'll give you the straight answer.

RED -> Fuel Pressure Regulator

BLUE -> Nipple coming out of base of lower intake plenum pointing towards firewall

YELLOW -> Rear rotor OMP injector (that nozzle pointing up out of the block with a thin oil line comin from it)

I'm not sure what you've got going on in your description.

 

Thanks that answers my question. I'm glad you understood what I was trying to say cause I just reread what I wrote and I realized how badly I worded that.

Thanks to everyone else too, that's a very nice diagram Wargasm!

 

Sounds like Dave is taking the solenoid out of the picture and routing it straight to the engine. I guess this elimates the worry of the solenoid failing, but I wonder if there are any drawbacks.

 

I did the same thing on my car when I installed my single turbo.

All that solenoid does is temporarily boost the fuel pressure by a few PSI on engine startup and hot starting situations... I can't tell that it's not there... car runs fine.
