R&D Power Pump vs. Power Bowl

[tsargent4]

What are the differences between the two? I looked at both and they seem to do the SAME thing, different prices. Do the two have to be used together or seperately? Which is better for the money?

both products are awesome imho....

the bowl is advertised to reduce anti-cavitation.... whereas, the power pump is specifically designed to improve the AP performance...

I've used both on my customers carbs and think they are worth the money..
