the PE 4450 fuel pump/filter combo in my car has been there since it was built in 2004. It has always been dead headed until earlier this year without one issue.
Further, I sent it to John earlier this year for inspection, feeling guilty after running it for 12 seasons and he said there was nothing wrong with it. Again, the bypass won't do anything for the OP except lighter his wallet by ~ $200 but if it makes him feel better, get it.
