guys im fitting a monster tank to my damaged xtr and just have a question... the monster tank has 2 fuel lines (one in and one out), the xtr has one. Is one a purge line or something? The wiring of the pump & sender should be an easy mod, but I'm also wondering about the fuel pump. could I use the duc pump as well or would it put out too much pressure? or not enough? anyone have any ideas on this?
