It seems to me like the valves open and close based on pressure differential. If I was a valve, I don’t think I’d be able to know, or care, how that differential was created, Mike Moore On Mar 2, 2015, at 2:16 PM, Ryan Hill ryan_hillc300@xxxxxxxxxxx [Chrysler300] <Chrysler300-noreply@xxxxxxxxxxxxxxx> wrote: John, with all due respect. You were just stating you're replacing your mechanical pumps annually on all but one of your cars. Are you certain it is only due to ethanol? Is it possible the failures are linked to pushing fuel through your mechanical pump while the engine is not cranking or running?

Are any of you guys experiencing pump failures using electric auxiliary pumps to prime your systems? I know they're low volume pumps that are generally being used but wondered whether pushing fuel through a mechanical pump could do any damage to the valve/diaphram?

I
think the newer materials being used to rebuild fuel pumps may be more
resistant. Comments will be appreciated.
