93 f-150 warm start

Maybe fuel pressure regulator is leaking
Mounted on fuel rail under the hood... depending on eng size 4.9 on right side, 5.0 and 5.8 is on left rear I think... Anyway its on the fuel rail and is sort of round. It has a vacume line coming off it When it goes bad fuel will come out of this vacume port and flood engine,, may also run rich |
