1989 f350 petrol running extra rich
#23
My fuel pressure regulator was bad. Replaced it..my 1995 f350 7.5 460 came to life! .
Sorry..first time on here..wrote too much up top..I need help! My 1995 f350 had no power at all. Fired right up and idled ok..sounded sluggish. I replaced plugs wires rotor distributer and coil..no change. Then..I changed the fuel pressure regulator and boom...amazing truck..I mean wow! What a hoss....for two days. Then I felt it change. Got another day of decent performance. And now it's leaking and even spraying fuel from the regulator again..what would cause this? Please help!

When you say spraying from the regulator, where ?
The regulator is usually held in place with 2 or 3 allen head screws. Usually "O" rings under it's mtg..
If the regulator is a cheapy from a china aftermarket supplier , questionable quality.
The fuel pump in the tank will supply sufficient pressure and the regulator is what is controlling just how much goes to the injectors and the rest goes back through a return line to the tank.
Does your vehicle by any chance have dual fuel tanks?
