Take the valve out. Fuel pot? on vent line? I just removed the valve and now have no surging. Double check the lines off the module, mine had been changed and the return was to the vent line. Car still ran fine until under a 1/4 fuel. 

 

Is the car stock standard boost etc? Why running walbro?

Are u talking about the valve that's in the return line for preventing fuel vacuuming back up ? So your breather line is obsolete now ? I'm working my way towards 300kw. I installed a boost gauge the other day on wastegate line to see what my boost is sitting at and apparently its 2.5 which is way under. And the fuel pot for the standard pump ? Believe it's for surging

No the pressure valve in the module/assembly I removed and hooked back up to correct line. Sorry I don't know what you mean by fuel pot? Are you using the original fuel module with walbro pump or new larger module with walbro pump?

So send and return are the two outside ones and the middle is the breather ? The standard pump has a fuel pot but if u install an aftermarket pump like the walbro for example, u need to put the fuel pot surround on new pump or get an aftermarket surge tank
