I was wondering which one you would recommend and how exactly do you set these things up? Also wondering if these are any cheaper than buying an airdog.... Thanks for any info.

 

they are much cheaper, the blues run around $100 and the blacks are around 150. i got mine for 160 from summit racing.

The holley blues are 110gph at 14psi.

The holley blacks are 140gph at 14psi

Its nothing to set up, bolt it on, splice it in the fuel system, wire it in and your done.
