Looking for some help and advise please.

I'm currently using a Walbro GSC404 in tank fuel pump that is rated at 80 lph on a 2 cylinder turbo engine (webber) that is in a hydrospace jetski.

We have done quite a few mods now so I am worried that the current pump my be the weak point for the future dyno session we have planned.


I cant find any data about this pumps flow rate other than 80lph

I need to know what pressure the 80lph is measured at?

Is there another pump with a higher flow rate I could use instead??

We need enough flow rate to support 300hp a 5 bar line pressure
