Fuel pump question

Does any one know how how to test a vacuum fuel pump on a Suzuki LT250? How much pressure should it have or how much fuel it should pump? There are no specs that I could find on this.

Unhook the hose that goes to carb one that does not have a long spring get a gas can and short hose to pump gas in can and start turning it over and see how good it comes out and some have a vacuum petcock that shuts off too and if I ain't sucking or not right that could cause it too

and is it a quadrunner a 4x4 high,low,superlow and etc.

It is not serviceable,so pull the fuel line goung to carb,crank engine over and see if fuel passes through.it would have very little pressure to start with..

If it dont work we will fix it while we have our dirty clothes on.Best experience is hands on experience.
IF IT AINT BROKE,DONT FIX IT.

I know HOW to test it, I want to know if there are any specs such as how much fuel it should pump per minute or what the fuel pump pressure should be.
