Mechanical or electrical fuel pump

I always use mechanical pumps unless I have no choice. I prefer the simplicity and most of all the silence of a mechanical pump. I have a 440 in my Gold Duster. Not sure about how much power it has but it weighs 3500# with me in it and has run a best of 7.06 @ 96 in the 1/8 mile and 11.125 @ 121 in the 1/4 mile. The 60 ft times are in the 1.50s with a best of 1.545 and I currently have 5.29 gears in the axle and also an A-518 overdrive trans. I've also ran 4.57 gears so I estimate its making around 550 at the crank. I have a Clay Smith Engineering pump, 16 psi and 160 gph. The rest of the fuel system is a Holly 850 DP, a JAZ 16 gallon fuel cell with 3/8 aluminum fuel line to the pump and I use a simple Enderle check valve as a bypass regulator. The bypass goes to another 3/8 aluminum line back to the fuel cell. No wiring, no switches and best of all no noise. I've been running it since June 2014 with no issues at all. I have not been to the Clay Smith web sight in a few years so I'm not sure if they're still selling the pump. If Clay Smith no longer sells the pump you may be out of luck because when I searched for the right pump it was the only one I found with enough fuel volume. If you do go electric and its a street car I recommend spending the money on a good high quality pump that is not too noisy. Magna Fuel, Aeromotive and probly some other companies have them. I've had a couple of Holley blue pumps and they are very loud, like an alarm clock buzzer.
