Electric or Mech Fuel Pump? For a carb...

I modified mine to accept a pick-up tube that I fabricated.After removing the 5/16 line, I peened the hole to accept the 3/8 and soldered it in. 3/8 socks were still available at the time from the local dealer, although I bought the last two he said were available. The hardest part was reinstalling the electrical device.
