Which of the two is better and better flow? I currently have a INlienfuel pump with my jrsc. I ran into detonation on 6lb and everntly blew. Was it because the inlinefuel pump maybe shortned? Besides that factor..which of the two is better for the jrsc and etc: Thanks personaly opinions are welcome.

I'm not a very big advocate of inline pumps, i'm more partial to intank pumps. The whole push/pull operation doesn't sit well with me. If thats the pump that came with your kit, then i doubt it was the cause of your problem, could have been timing related, poor gas, or poor tuning (clogged filter,bad plugs, pump connections not good)...
