Fuel pressure vacumm line.

Does this line simply work off of intake vacuum/boost levels? I'm not getting any pressure on mine. Followed it back and it seems to be fitting on a nipple on the bottom side of the intake close to the coil pack.

Boost gauge is getting normal vacuum, so why not the FPR?

Can you take a picture of the port this thing is tapped into? The FPR *should* be getting engine vacuum/boost direct from the intake manifold. Where is your boost gauge tapped from?

Never mind. I tested it hot shortly after turning the engine back on. I was doing all kinds of searches trying to find the path of the lines and re-remembered that the FPR solenoid was cutting off the vacuum after I turned the car back on. Tested it again later and its fine.

It should recieve full manifold vacuum.
