Re: [Chrysler300] 300H Fuel pump problem

I agree with Jeff that there's a potential risk of diaphragm rupture putting
fuel in the crankcase, but it doesn't seem to me that it's heightened by
having an electric pump operating at the tank while the mechanical pump
merely sits there having fuel flow through it. That said, I wouldn't use an
electric that produced more than 6-7 psi at the engine.

If appearance isn't a factor, the pump can be removed and the hole blocked,
as Jeff has done. If appearance IS important, maybe going into the pump and
removing the outlet check valve would reduce the risk of overpressuring the
diaphragm.
