Fuel pressure gauge installation.


Registered User
I'm wanting to test my fuel pressure ready for further mods.
I'm looking at getting an inline fuel pressure gauge.

Can anyone suggest the best location to install it. I'm guessing its just a case of cutting the fuel flexi line adding the brass t-piece with good quality jubilee clips and checking all totally sealed.
Where have people installed theirs?

Is there a schrader (sp) valve on the fuel rail?

I bought an inline adapter from demon tweeks that allowed a 1/8 BSP thread. It depends on the size of the sensor though. Most decent ones will be 1/8 BSP or NPT. I think the inline mechanical style ones are the same.

I went with an SPA dual boost and fuel pressure gauge but I've yet to install it. They're pretty much one of the best in the game so worth paying extra for. The loom and sensors are top notch (as is the gauge of course).

Now that I've got an aftermarket fuel pressure regulator, the sensor can fit directly into that which is cool.

With regards to the location, anywhere between the pump and fuel pressure regulator. So basically the feed line to the fuel rail on the drivers side of the car. Remember to use proper fuel line clamps and not jubilees.

I'm looking at something along the lines if this-


Not wanting any additional gauges within the cockpit if can be helped.

How do you mean by fuel line clamps. Are the like jubilee clips but slightly different screw clamp design? Like this - http://bit.ly/18rYg3d
