I bought one of the Tsunami in line pumps but immediately returned it to Jegs without even opening it - I read all the posts I could on their stuff and very little seemed to be good. I have a Walbro in line pump now - works great - I have heard almost all good stuff about this brand. I was worried about using the Tsunami in continuous street use because people were saying that they are intended for racing not steet use and some people say to put a control box in for the pump? I never did figure what all that junk was about but I figured I was basically stock and did not need the overkill and saved $200 in the process.
