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...
