I wanted to buy a complete kit so I went with the external pump. Everybody says the Tanks with the Walbro pump installed is the way to go but it meant ordering that separately and more expense so this the way I went and now I'm stuck with it( at least until the pump gives up). Should be fine. I've heard from guys that have been running this way for years without issue.

More of a concern for me is if the system will be able to adjust to my driving conditions. Different parameters can be tuned in but with the cheaper systems there is only so much that can be done.
