Andy, Be careful when removing the big nut at the end of the rail, there is a sealing steel ball that easily falls out and disappears. I don’t know what the fitting type is called, but it appears to be the same as the input to the dampener.

Matt, on that point you speak my mind quite well. Also any fuel filter clogging, nicked fuel line and inadequate or tired fuel pump, will show up first at max power (max fuel flow) where the consequences of problems are most expensive.

Here is one option for an electric fuel pressure gauge.
The sensor could be installed at the end of the fuel rail by cutting, drilling and tapping 1/8” NPT thread (as I did, but with a bulkier sensor), obviously with the rail off and being thoroughly cleaned.

Thanks for the tip Laust. When I pick up the gauge I'll remember that, I think it's best if I just put my hand underneath it when unbolting it

Unless you have a specific tuning problem that you are trying to solve, I would recommend not installing one. Those mechanical gauges do indeed fail, with severe consequences, as Matt pointed out.

Laust, did I understand that you are currently developing an incabin gauge? That would be cool!

I have the Autometer 3363 installed under the radio in the cabin (next to boost and a/f ratio gauges). I highly recommend it.
