Replacing stock fuel pump with LT4 pump


Recommended Posts

So I'm getting codes p0172 and p0175 which seem to often point to a bad fuel pump. In 2025 I'll rebuild the engine and supercharge it so ill need the LT4 high pressure fuel pump. 

Is it a fairly direct replacement  that doesn't require tuning? 

I assume I'll need the LT4 injectors to utilize the pump. Are there any other supporting mods required?

You’ll be needing a stronger in tank pump. Something like a single 535 or dual 450. Depends on HP goal.
