I just figured out I have two different expansion tanks for the FE. One has the cap on the side of the Inlet the other is on the opposit side. Looking through bunch of pictures seems like both are used with the majority of being the one with cap on inlet side.
Which is the right one? Or both? Thanks.
CSX3288 and CSX3020 have their cap on the front side of the exit port. ei: front left of expansion tank once mounted. Neither have the cap over the inlet port.
