So my 88 F-350 has the white fuel heater and the one i have for spare is black. Are they interchangeable? i remember reading from my thread about the o-rings that the white one has two o-rings and the black has one. Can anyone confirm this? I havent torn mine apart yet, as its playing lawn ornament until i get time, just would like to know before hand.
