Fuel Pressure Gauge - Electronic or Mechanical???

[joecool911]

Vulcan has little push connectors for the gauge back and isolator end of the 1/8" pipe. You can even push on the end if the fitting and remove the line as needed. I drilled a hole in a pop bottle cap so I could use a pop bottle to fill the line it out stopping and flushed while a helper shoved the isolator end into the slip fitting. I believe I evacuated a lot more air this way than fooling with compression fittings. The olive on the compression fitting crushes and is made for one time use. I ran mine down an electrical tester probe, which comes to a needle point and gets progressively larger. Used a crescent wrench to put pressure on the olive and was able to re-expand it to fit over the 1/8" hose. But the quick connects for obvious reasons are much easier. Multiple on/offs without damage to the piping or fittings. :thumb1:Then a schrader valve inline before the isolator so you can bleed the isolator without messing with the bleeder screw, which was not sealing without Locktite on mine.
