The fpr at the engine fuel filter housing leaks a drop every couple seconds or so. Is there an o ring there that I can replace or do I need a new one? Just bought the truck a few weeks ago so I'm still a newb
Well, since there is an updated fuel pressure regulator spring kit, that comes with a new cover and the necessary o-rings, why not get that? It will raise your fuel pressure close to 70psi, while the existing spring is known to weaken over time and could allow the pressure to fall below 45psi. 45psi is the absolute minimum pressure, below that and injector damage will occur.
