I run this one with 3/8 line and 3/8 pickup works great:

Yes, I use that same pump on my hot street 318. I noticed the pressure was way up there, 11-12 PSI, at idle! So after a while I had to install a regulator...I used the cheap Holley 12-803 deadhead regulator.

here's proof!



then just plumbed the regulator, runs at a constant 6psi.
