1976 to 1980 450 V8 and 6.9 2-Hole Fuel System Accumulator
This accumulator was unique in the mid to late 1970s. It was used on all 6.9s but only some 450 V8 models. That is why you MUST know which type you have BEFORE ordering. You can clearly see the two threaded holes coming into the front of the accumulator housing.
