Just finished installing fore l1 dual pump system on my 2015... Have noticed after shutting off the car, fuel pressure drops from 43 to 5 psi in 30 min or so.
'
I've confirmed no external fuel leaks & also was able to pull the feed & return off the hat + disconnect feed into check valve without any sudden pressure change at the regulator (continues to slowly drop)
1) what do you guys see as far as pressure drop after shutting off the car?
2) if I've disconnected the feed into the check (no fuel out of check) & taken the return off the hat, the fuel has to be going into the rail/injectors right? So bad injector(s) maybe?
