I was unable to buy a "1970" fuel pump; 1979 was off-the-shelf. I wonder if you could simply install a three-legged fuel filter, and run the "return" line into the line from the tank and into the pump with a tee! The third leg is basically an outlet with a restriction -- it makes the pump "leaky". The third leg/return line also bleeds pressure off the needle and seat when you stop the engine -- this stops a lot of older cars flooding when parked. That's a nice thing!
