Holley pump?

I've been running the blue behind the stocker, over two years and still going.
 
some friends of mine are running black. that is what i am going run on my pulling truck
 
I ran the blue for a while, but after the injectors I could pull it down to 3 psi. Not good. That was with 1/2 lines and a relocation kit too. My friend has a Walbro and it does really well. It's not much more after the pump and kit if yo go that way. If you do get the Holley get it from advanced or autozone, they have a 1 yr no questions warranty.
 
do you guys run these over fass or just over stock? i havent ever seen much about them, someone fill in the village idiot!
 
Many times they are run in conjunction with the stock pump.


I'm on my fourth Blue in three years, I would go with the Walbro.
