getting a new fuel pump, and might be sprayed or blown in the forseeable future, and wondering if i have to buy an adjustable FPR if i get the hi pressure pump as opposed to the std pressure 255lph..
i know i will later, just want to know if i can use the hi pressure pump right now w/o an AFPR, so i dont end up having to buy another fuel pump later on.
From my understanding you can not utilize the factory Mark VIII FPR for too long with a high pressure fuel pump. From what I have been told the diaphragm inside will eventually rupture. You can get a Kirban AFPR here, same place I purchased mine from....along with the fuel pump (GSS342).
I've been running the Walbro 255 (not high pressure) in my car with the stock FPR for over 2 years now with no problems. I also ran out of gas one time and the Walbro is fine.
