I've installed a VL exterior fuel pump to the Geep, and since doing that, I've noticed the Fuel Pressure Gauge is pulsing, and when the bike is turned off, the pressure drops immediately.
It's my understanding the fuel pressure should hold for a while after the bike is switched off, and bleed down slowly.
There doesn't seem to be any running problems, and the bike fires instantly, as per normal, so maybe it's not an issue,but it just don't seem right.
Any thoughts??

The pressure should drop, you dont want high prssure fuel lying around.
as long as the pressure is around 40 psi when its running, its fine
