Low Pressure Fuel Sensor Install

jibarra · 01-04-2022, 09:55 AM

After doing some logs, I found my low fuel pressure pegged at 72psi. Car drives fine so we think the sensor just went bad.

Before I dig into in and start removing parts I don't need to, does anyone have a guide or video or has done it in the past that can share some details? I'm very hands-on and able to do it the work, but I've just recently gotten the M3 so it's a fairly new platform to me.

just changed my low pressure pump, ( under the back seat ) , I tried a high output pump, it was trash... stick with a stock bmw replacement...unless your making big power or full e85....its not hard but it's not easy either , with all the plastic lines etc.
