I agree with Corey, your shop sucks!!,, My mechanic installed the FASS on my 3406B in short order and then he removed it and reinstalled it on my DDEC IV, I don't have any fuel mileage figures or performance statements but it works by eliminating the air, I like the FASS if it only supplys the main fuel pump with pressured fuel instead of vacuum, ALSO, I agree with FASS customer support "SUCKS""""""""""
