Re: [T3] Measuring fuel pressure -- hose size and fitting?


For the gage, just get the right nipple to fit your standard FI fuel line.  The nipple on the fuel rail accepts the same size of hose (~5/16") that is used throughout the car.  Just press the hose onto the nipple.  You can use a small hose clamp if you want, but I don't think I have ever bothered.  If you use a segment of hose that reaches to the front seat, you can monitor the fuel pressure under load (e.g., while driving around the block, up hills, etc..).  This is a useful test.
