Idea for single pump setup

[tubular031]

I came up with this idea a little while ago when brainstorming with Matt. This setup is mainly for the OBS guys looking to replace the lame stock fuel pump and run veggie. This is kinda a hybrid version of the veggiestroke and sunwizards design.
Let me know what you guys think. If it works like I think it will, this should be a cheap way to convert an OBS BUT there is only 1 pump so you do not get the dual pump redundancy like there would be on a SD style conversion. The pump on this setup would need to be internally regulated like a FASS pump.

Let me know what you guys think. Sorry for the wonderful drawing

I think it looks good. A drawback would be that you would wind up with a longer purge time than the two pump systems with check valves very close to the heads. If you wanted, you could replace the purge valve with another 3 way valve to be able to run a regulated return, which would open the door up to using different pumps, though if I was using a single pump and running veg through it, I wouldn't want to trust anything less than a burly FASS.

I like it!
