Ehh......I would prefer the FASS system. Just the design of the fass and it being able to seperate air from the fuel seems like the best benifet, especially for us VP44 guys. I haven't heard of any trouble with the FASS electric pumps them selves.
But do some research on those FASS guys. Father and son stabbing each other in the back, questions of legality and patent infringement, apparently some questionable customer service issues, questionable physics of exactly HOW it's supposed to work and achieve it's propaganda claims, inability to answer some basic questions on those claims and (apparently) flawed physics, etc. I don't recall all the details, but there was a long discussion on another board over a year ago where both father and son gave (IMO) a !VERY! poor showing when called point blank on some of the BS by engineers who know a LOT more than I do. I would just go with a good lift pump and a readily available 2 mic filter like the CAT, spend 1/10 the money, and call it doneā¦
