Pump overheats after 10 minutes at idle and fuel pressure drops to zero. Called Holley and tech said the pump must be at the bottom or below the cell. It is meant to be gravity fed. They are meant to push fuel and not have to pull it up from the cell. Multiple other people verified this about these type of external electrical pumps.
So what's the deal? Every Panoz I've seen has the pump mounted up over the cell. Is there some other brand/type of pump that is meant to pull fuel up out of the cell?
The car worked "OK" before but we did have some instances of the car cutting out. We attributed that to fuel cell foam breakdown, but who really knows. The Holley tech guy said he's seen people mount them as shown above and get lucky and have them run for years, but it's 100% not meant to work that way.
Said the top cause of pump failure was mounting location. The second was incorrect wiring i.e. insufficient gauge wire. Not an issue here as the pump is on its own circuit and wired with 12 gauge wire.
Thanks,
