IT has to be my stock pump

I have all ready done that,what are you saying there is no way that pump can deliver to much pressure?
You said earlier that you,ve had no problem with flooding the past 5yrs,so I,m guessing dirt has stuck a needle causing flooding.If you,ve had major flooding and everything is OK now...change oil immediately before running the engine anymore.Stock fuel pump seems to be working again with no more flooding, leads me to believe DIRT in system JMO
