Q: Replacing fuel pressure regulator

asked by on December 21, 2016

So my fuel pressure regulator needed to be replaced so I bought a new one and tried to do it myself. And I take out all of the o rings and screens from the old one. And try to put in the new one. And I try for a few minutes but the new one will just not want to seat all the way so I try to take it out and I wasn't thinking and I pull the regulator and the screen stays in and when I take the screen off the small o ring is gone and must have fallen into the fuel rail. So is it difficult to remove the fuel rail??
