I have an 1987 chevy s-10 blazer with a carburated 283cid engine. Fuel pump is in gas tank. My vehicle starts running poorly and I notice my fuel pressure regulator reads 2lbs so I turn it up to 4.5lbs runs great for a few miles. Then the pressure reads 2lbs
i have to keep adjusting my fuel pressure regulator back up to 4.5lbs do you think my regulator or my in tank pump is going bad?
have the same problem?
