how to tell if fuel regulator is bad
Your truck won't run right due to inconsistant fuel pressure. What are your symptoms that you suspect the regulator?
To test the regulator, get a couple feet of the 1/4" clear aquarium hose. Put the hose on the regulator nipple and suck on it. If the regulator is bad, you will see gasoline traveling up the tube.
