i have been running a 1st gen Pro-flo for close to 20 yrs now...other than 1 fuel pump replacement, have'nt had any issues...
any reason why you don't run it anymore? i too have thought about upgrading, prob to the 2cnd gen hardware.
and that LOUD annoying hiss i belive is your air filter...
when i run this cleaner (ya, it's ugly...) the 454 is quiet as can be, no air hissing or roaring...
but i am currently running an open element cleaner right now, which does give that annoying hiss. i find after the truck is warmed up, it goes away, and strangely, i find it gives me just a little more power/driveability in the mountains..
