Ruff runner

Certified mechanic put new gas tank;lines;and sending unit. Drove home a half mile ran fine. Started 3 days later, hardly ran. Oil smells of gas. Put new spark plugs in and gapped corectly. New distributer cap and rotor. New map sensor. Still hardly runs. Also smokes out exhaust, never smoked before.

Any ideas?

Best advice is to go back to this so called “Certified mechanic”. Ruff, Ruff! GRRRR! Bow, Wow!

Bad fuel pressure regulator.
