fuel pressure gauge???
What size is the threads at the end of the fuel rail on a 928S4??
I am looking for a rail mounted fuel pressure gauge... I remember seeing one on Specialists but can't find it?
I looked online, but everything seems designed for dash mounts, not underhood mounts? I just want to mount the pressure gauge right at the end of the fuel rail?

Carls is pricey, but it will drop right on?

For the one DR recommends (same as what I have) will require you to drill and thread the cap on the end of the fuel rail. Carl's includes this part so his is no fuss no muss.

Most of us just drill and tap the fuel rail cap with a 1/4" pipe tap. Any industrial gauge compatable with fuel will work. (Needs to be the correct pressure range) and liquid filled provides a more stable needle. I paid $9.00 for a liquid filled gauge at Grainger about 3 years ago, so my total cost was just that, $9.00.
