I have seen where there are two replacement fuel tanks. One is with ECU and the other is without ECU. I was told that the difference is that one has 1 vent hose on the right side. The other has 4 vent hoses on the right side. I have tried to look at my tank while it is still in my car. The only thing I can see on that side is the filler neck. Can anyone offer any help?
Does type of car and engine make any difference? My car is a '70 SE that originally had a 318. As far as I know, my car was never a California car, so it most likely did not have the emissions stuff on it.
I appreciate any insight.
