Which Walbro do I have?

[eclipsh]

So I dug around on Walbro's site and vendor sites and cannot figure out which size fuel pump the last owner installed. It says it is a "315." Is that the 190 lph or 255 lph or something else entirely? Thanks for whatever help you can give.

Walbro GSS315, which is what you have, is a 255lph non high pressure fuel pump.
