I had a prof. welder weld two octagon shaped 3/8" pipe caps , that I drilled the end out of , to the same size as the inside threads .
After he welded them I took a long tapered punch and drove it thru the couplings till it wouldn`t go any farther, then simply screwed my fittings into the couplings. I added two 3/8" moded dhut off valves, which go into normal 1/2" in line filters , then into a home made alum. "y" , then into the fuel inj. pump. Don't have any pics at this time---------aint promising I can get them on here, but will take a couple and try.
