Quick question on Walbro Pump part #?
 

I know the GSS342 is the 255, but does anyone know what model the GSS317 is?

Thanks

gss342 is high pressure 255lph which can go past 90psi and still flow decent amount of fuel around 27 gal/hr

the gss317 is 255lph but only flows up to 90or so psi and after that it fall flat on it ass

Thanks Viren

I knew there was the 255 and the 255 high pressure just always thought they shared the same part # with two different versions https://honda-tech.com/forums/images/smilies/emthup.gif .

i always stick with the high pressure unit usually works great last abotu 2-3 years of good service life and it can handle up to 550hp not a prob at low fuel pressuer they flow damn good at 40-60psi of fuel pressure.
