| 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. Bill
