Rusty,
I have been using a three-minute electronic timer (home-made) to transfer fuel. The Facet pump moves about one GPH, so every time I push the button, I get three gallons. Works great for lateral trim.
As for the fuel pumps, I only run on one except for takeoff and landing. When I do a run-up, the last thing I do is turn on the second pump and watch for a 2-3 psi increase in fuel pressure. That tells me it is working. At 1000 feet agl, I turn off the second pump. My theory is that by only running it for takeoff and landing, it gets very little wear and the filter will last a very long time. If the primary pump or filter go south, I have a fresh pump and filter to take the load.

I'm still not completely satisfied with my fuel system. It's hooked up just like Tracy's, and maybe I'll like it better if I ever get that automatic fuel transfer timer set up. Hey Ed, weren't you the one making that at one time?
Cheers,
Rusty (young whipper snapper to you)
