Are these 2 pumps the same. i just got back from Auto zone and had both side by side and they appear to be the same size and shape except for two small electrical connections. i heard the typhoon and clycone pump flows more fuel then the stock z28 pumps in my 91z28. is this true and if so wouldnt it be better to put in the typhoon pump.

 

I definately wouldnt' think so. The cyclone was a Supercharged 4.3. I think it would put out more fuel.
