190 or 255 pump?

[1fast97gsx]

How can I tell the 2 apart? I bought the car with a pump in it but the reciept doesn't say which one it is. I'm assuming it's the 255 but I want to make sure. Thanks.

well, I guess you can take the whole assembly apart, and check part numbers. Match any of these:

If you really want to run 10s like your sig pronounces then your gonna need something bigger than a 255.
