Hi folks, I'm getting a high fuel pressure reading at the rail on my 1998 v70 t5. It is 65psi at idle but 43.5 when just primed and engine off. I have fitted a new fpr and checked return line for blockages. The fuel filter is newish and I have a new walbro pump. Been doing some logging and it is causing the fuel trim to lean out so I need to get to the bottom of the issue. Anyone had anything similar or got any ideas? Cheers

Gareth
