Hey guys my car has been running kinda funny the past couple of days in that respect i mean running lean.....but anywayz i pull off the fuel return line and no fuel came out of the secdary rail like it usually does.....what could cause this??

 

clogged line to the rail? leaking injectors?

 

Have you changed your fuel filter?? Are you running the stock fuel setup? Or aftermarket fuel rails and FP?? Parallel fuel system??

 

i have changed the fuel filter 720 cc all around stock rails walbro 255

 

Could the voltage reg be the cause???
