You guys think a Fass is necessary with the cp3's?

A fass supplies the fuel to the cp3 and if your truck is asking for more fuel than your stock lift pump can supply your cp3 can run lean. It wont live long doing that.

a fass pump is a one time pump replacement and they have a lifetime warrenty

Im a FASS dealer and they are rated for 12,000 to 15,000 hrs of use. Big tunes need lots of fuel and the fass pump will get it there for you.

Yes. The stock feed pump on a Dodge has a hard time keeping up with a big tune. Two CP3 pumps with the same tune will not use more fuel, but if your tuning asks for more than a single pump can handle, which is why a person would use two CP3's, then you definitely need a better supply.

LOL, thanks for the info but this was a really old thread. I'm good to go.
