FBI sucks ass I ordered some flapper valves for my thomas comps like a month and a half ago i also ordered two pressure swithes cause the guy gave me a good deal on buying 2 of the. Well about a week later i got my order no flapper valves so i called them. they shipped them out agian they said I had ordered 4 of them so i would have 2 extra for backups. Needless to say when i got my order for the 2nd time I only got 2 flapper valves. I called them agian and they said they would ship the other 2 back out. THREE WEEKS later still dont have them. Ill never order any thing from them agian. Very disapointed and pissed:rant:
