I currently have a 150 fass on my truck, I use no bypass or fuel pressure regulator for it. I switching to a walboro GSL 392 pump I noticed in glaciers set up they use a bypass system back to the tank do I need this or can I just plumb my pump in and go?

 

You have to use it. Otherwise there's no relief and you'll have 80psi all the time. The Walbro doesn't have a built in regulator like others do

 

Where can I get one?

 

give Richard a call at GDP

 

Ok thanks alot
