Fuel pump options

For 200hp I would upgrade the fuel pump, especially if it a 27 years old pump

The easy rule to size your fuel pump:

Flow of your injectors x number of cylinders x 0.06
(0.06 -> x60: minute to hour, /1000: cc to liter)

Exemple for a blacktop:
295cc @ 3bar
295 x 4 x 0.06 = 70.8 l/h

So the minimum flow of your fuel pump should be 71l/h @ 3bar
(Personally I prefer to add 20 to 30% to this number as a safe margin)

Well...I dont think fuel pump can still make that much after all these years...
