We had a purchasing mistake for a client and we ended up with a 89-95 walbro 255 pump off ebay for his 87 TII. Now I have been checking several places and cant find if this would be a problem or not?

I could always throw it in my 93 and order another one, but this was only $56 .
Looks like either kit contains the same pump, but a different installation kit? I will pull the stock pump and compaire.
