fuel pump help

[1990gsx1781]

i just ordered a new 225 fuel pump dumb me didnt notice it said 225 hp but they also list a 225 lph whats the difference if any... also i read the descriptions for both and it didnt say any difference.

only thing i have found is the 225hp is high pressure.?

yeah, the HP is high pressure, which flows more than the regular 255 at higher fuel pressures. An adjustable fuel regulator is highly recommended for either pump

It's not about blowing the lines, its about overrunning the stock regulator with the increased flow. Search it up before purchasing, its a heavily covered topic
