Fuel system electrical - stupid design

[Gearheadvr4]

I stand corrected. Like I said it's been a while since I read the schematics. I went thru all that a few years back with a electrical ghost that took a week to track down.

Appreciate the info.

I know for a fact that my Walbro does not have a check valve in it to hold the pressure. I run a Fuel Lab FPR and it held pressure fine with the stock pump. Once I installed the Walbro it would not hold the pressure anymore and would drain the system in about 2 hours. I am going to install a check valve right at the pump at some point as the hard start due to no pressure is driving me nuts.

Glad you posed this, I installed the walbro and afpr at the same time and assumed the afpr didnt hold pressure. That check valve might be on my todo list now haha
