So, I have been knocking off some minor projects that have been sitting on the shelf - for a while

One of these was placing my fuel pressure sensor in the fuel rail. The gauge was already mounted and powered, and the sensor plug was already positioned in the engine bay. What I needed was for some way to place the pressure sensor in the fuel system with little or no modification.

Then I stumbled upon this product:

It basically acts as a spacer between the fuel rail and the pressure regulator with a port out the side for a sensor. I got the dimensions off the company and they were pretty close to the SP20 application. The bits where the fuel travels through are perfectly fine for an SP20, but I had to enlarge the mounting holes a bit to bolt it to the fuel rail.

Applying it to my fuel pressure regulator looks like this:

I don't have a great shot of it on the engine but you might be able to spot the flash of silver in a later photo

All-in-all, a fairly simple and easy install once some minor modification has been done
