Fuel pressure climbs at idle

For around town sure; you hardly need any pressure around town, but you do need volume.That's the nice thing about the mechanical pump; Low delivery at idle and volume rising with rpm. And the HO pump only puts out about 8psi dead-headed.
I had a nice Edlebrock 110gph mechanical pump, loved it but when it was hot and I would go to wot it would sometimes fall on its face. The reason for going electric.
