Southern il | Have a 7420 that has had all fuel lines replaced, found out there should be an in line orfice in return line from fuel filter housing to the tank. Part # L167846. I have one now just not sure which direction it needs to go in the line any help would be appreciated. Should small port go towards the filter housing or the full port?
