Walbro fuel pump question.
 

I was given a slightly used walbro fuel pump the guy said it is either a 155 or 190 lph pump.

Is there any way to tell cause if it is the 155 lph cause if it is it is too small for what I want to do.

Thanks,

if it's a walbro pump it should be engraved on the side of it.

Thanks I will check it out, It is a little dirty and needs to be cleaned up,

Thanks,
