Your question is What is the difference between 255liter/per hour and a 255liters/per hour? :-\ Well, it the "s" that is missing in the first expression!

You dumb frenchy the difference is the high pressure denoted by the hp not the 's' lol. Other than that I don't know what the pressure rating is on either. I have never noticed a walbro being louder other than when it primes just before startup.

The 255 LPH pumps are the same...EXCEPT the HP has a greater rated pressure at that flow... Therefore making more fuel available at the same rating. I have a dual Walbro setup and it works fine, ---- on stock fuel lines, well.... You alredy know what im getting out of the setup...
