I installed a new Vp44 and a new stock lift pump last week. I just installed the Fuel pressure LED kit today. I took it for a test drive and the light in blinking when I am going. It is not as strong as when it is full on like when I turn the key on. Does this mean low pressure already????? I am not sure what to replace from here. I will get some sort of gauge tomorrow but I need to get this fixed ASAP, I am leaving on a trip on Friday and thought my problems were over and I don't know where to pick up a FASS in MN?

 

I'm thinking you need to back up your data using a mechanical psi gauge. I've had a few customers come in freaking out about their LED only to find the electrical sending unit wasn't too happy with the fuel pulsation.

 

my first sender was doa.....
