My fuel pressure is playing up lately, I have 340l pump on a stock reg and sometimes it plays up on idle.... Some times it's on 34 then other times it's on like 43 or sometimes 48...... Time for an aftermarket reg??

 

yeah i would try an aftermarket fuel pressure regulator and see how that plays out.

 

That is really quite odd. Can you sit there and watch it change or is it just different every time you start it?

 

yeh itll change whenever it wants to....ive seen it drop with my own eyes once....it went from 45psi down to 34 now im just scared to go wot
