fuel pressure question
What would cause a pressure gauge to bounce (a little) at idle and cruise?
I seem to be having a hesitation problem and I got it traced to that I think.
At decel, the gauge is solid but when I get on the gas even slightly, the needle bounces. Not a whole lot but enough to notice. The regulator is an HKS and there's no leak in any connections. Te other night I noticed the gauge read 2.0 bar which seemed low at cruise and idle. I tried to raise the pressure but it's almost at it's max setting. The gause reads fine on boost and rises to proper pressure and stays solid. What would cause this? The gauge is a Greddy electric unit. Thanks for any help.
