i was just searching around and came across a thread about truck pulling and some of the top modified 12v guys. and one person said they run sigma pumps....what is a sigma pump? please excuse me if this is a dumb question, but i was just curious if it was a P-pump for like a marine app. or something?
thanks!
thanks!
