wasn't the first pumps 887 then they went to 913 (no internal difference). if the old guy can't see to read the tag on the timing cover. there is no way he is going to read the numbers on the pump. and best i could tell on my 94 a person would have to remove the throttle linkage bracket to see the id tag on the pump. but with my luck i fear it will be a 95 175hp truck. guess ill just part the whole thing when i get it.
