I have a 1997 jeep wrangler tj 2.5liter. I hooked up a fuel pressure gauge to the system and at key on it reads 10psi and at start up idle it reads 25-28 psi. Is this normal or to low of pressure. I can hear the pump whining when o turn the key on
It was low cuz the line went from a 1/4 size to a 3/8 hose line so I replaced it and now the pressure is 20 psi at key on and roughly about 30-35 psi at running
