Jumping fuel pressure...
I´m having some trouble with the fuel pressure on my -88 Camaro.
A year and a half ago I installed a Walbro 255 pump, this year I installed a Kirban AFPR and N2O.
Recently I have seen that the fuel pressure sometimes starts fluctuating or jumping up and down, about plus/minus 10-15 PSI and this affects the FPSS in the N2O-system.
With or without vacuum it´s the same, just different levels. It jumps rapidly, the gauge needle flips around.
Can this be a pump problem, a AFPR problem or something else?
I´d be grateful if someone can point me in the right direction to look.
