Question about Q45 fuel pump

[thekawaii]

hiI usually write alot in 240sx forum but i have a question,, i thought i should ask this here....I got a Q45 fuel pump from 1990 model with 90000 mile on it. I wonder what's the maximum Horsepower it can support.... I searched but i couldn't find any specification about this pump.OH! I only have a motor, is it okay to just replace my old 240 pump with q45 pump? I think i read, i also have to change fuel sock(?) too? Anything else to do? I know i have to change fuel filter too.

(I don't know if it will fit or not)

At 90K miles, that sucker is probably on its last legs.

Do you have the FPCM also? If the ECM you are using doesn't send the correct signal (probably from the TPS), I am not sure it will work.

Probably matching the interface is why so many 240 guys go with a Walbro.

All just guesses. Good luck.
