Fuel system issues
My fuel system is a dual external walbro setup. Tank is drilled, goes to a filter, then to the pumps in the rocker panel and on thru another filter. Regulator is set at 60lbs and a return line to the tank.
When I first put it in the pump lasted about 1000 miles and died. I put a new pump in figuring it was just a bad pump. I have a few hundred miles on the car after I put the new pump in and the last time I had the car out I noticed the pump was starting to whine again. Two pumps dying in such a short period of time cant be a coincidence.
Experts............advise me.

Not many pumps like living outside the tank. Most external EFI pumps (Aeromotive and Magnafuel) require a unit that controls the voltage based on demand. That's why I prefer to utilize the in-tank pump for driving and an external pump for support during WOT blasts only.

I'll look into those. I am making 700ish now but I'll eventually go bigger cubes and when I hit the track I'd like the system to be able to meet the demands of more boost and race gas.
