We just had the fuel pump replaced and the mileage has dropped 25-50%. We used to get 280 miles per tank and now getting 180.

What's going on?

Might have a blown fuel pressure regulator. Install a manual press gauge, should be 60-66 lbs at idle and should jump up a few lbs when the engine is revved, if it doesnt move when you rev, the reg is popped, or if it higher than spec it is most likely the reg
