fuel pressure regulator vacuum diagram..

[jaimster]

that makes sense NOT sure why previous owner had it like that ! where else would the FPR get any vacuum otherwise !!

I disconnected the hose going to the FPR there was no change at all almost no PSI at all thought that was weird then now it makes sense

i m gonna correct that as soon as possible . wanted to replaced some of these small OD vacuum hose any idea where I could buy those ?

thanks for verifying the diagram believe I m ON to the real cause of my high negative LTFT issues now..

thanks again
