After draining the water separator and then playing the "bleed the fuel system every time you start" game on our last camping trip its time to pull out the water separater from the truck. No shortage of muck inside it. I want to try and keep the stock one if I can get it to work. I figured before I put it back in I'd pressure/vacuum test it for leaks, but not sure what I should expect it to hold. Seems like it will hold but only if its in just the right spot, so I'm not too confident in it. Anybody have any thoughts on how much and how long it should hold? Might just end up puting a racor unti or something in instead.
