About to install a few parts before I go FI. My car is currently not FI, but I am going to install a AEM adjustable fuel pressure regulator, walbro 255, and change the fuel filter with a fuel pressure gauge.
Is there anything I should know before I install the FPR? Looks pretty straight forward. Unbolt and disconnect vacuum line, and replace (with new O ring). Is that it? Thanks
