Mechanical fuel pump

Ran across a 12-383 Holley fuel pump for sale. It says it has a 60 GPH, has any one used one before? Are the worth using over a stock 318 in a 71 dart? If it matters will be swapping intake and card from 2 barrel to 4 here soon. Thank you in advance.
No.
However it will introduce headaches with the car's electrical system.
I believe it's a mechanical pump. You don't need it even with a 4 barrel.
