Which fuel pump?
 

How do you tell the difference between the walbro190 and 255 fuel pumps?
Found one and don't know which one.

One flows more. There is also a 255 and a 255hp. Do you have an aftermarket AFPR?

I think he is asking how do you tell the difference by looking at it.

But I assume the part number should tell you what you need. Take a look at whats on the pump, and punch it in Google.

I have the 255hp with an aeromotive FPR in my own car but I happen to stumble across an aftermarket fuel pump and it was obviously a walbro but just couldn't tell which one. I will look tomorrow to see if I can find a part number on it somewhere.

It is just that it is attached to the hanger and I don't really want to disconnect it if I don't want it.

It's been a while, but I believe they are the same body, so you are going to need to get a part number off it to figure out which it is.

yup, same body, need the part number, etc. Mo is right. Take it apart if you're interested, otherwise, leave it :)
