Bill,
I have no idea why it crapped out. It was working fine the day before. I have finger strainers in the tanks and an inline filter (not sure of the mesh size offhand) before the pumps. This filter use to catch a lot of building debris and dust but has been clean of late. I have a big ol canister filter after the pumps and before the injectors. I have power at the pump but even though the new filter came in today, I will likely swap the auxiliary pumps power to the primary just to verify the power test. I have heard of problems of running the pumps dry and avoid it, however, I have done do a couple of time unwittingly for a number of seconds. Perhaps the damage was done and it took a while to manifest itself. Chris Sent from my iPhone 4

Chris,
Why did your pump crap out? Is there something caught in it? Did you run
it dry? They are supposed to be good for about 5 minutes running dry before
they crap.
BTW
The bigger pump (391) is more than you normally would need, but if you lost
your alternator and were running on battery, the larger pump will maintain
the fuel pressure for a longer time. (as your battery runs down.)
Everything is a trade off. Tracy may get a pump to you faster, the CA place
is about $20 cheaper. They claim 2-3 day shipping...free.

What is the part number of the newer fuel pump Tracy sells, the ones that
has screw on fitting. My primary stopped working yesterday as I was showing the plane to a guy who
just bought a Velocity SE retract sans engine and avionics. He is
considering a rotary The auxiliary pumps is still hanging in there. The primary is getting power
but is silent. I would like to see if I can pick one up locally as I am
grounded until I get one. I searched the archives but they are less than search friendly. I found the
part number of the push on and clamp version (heck, I may have a pair of
those that I removed)
but I prefer the screw on that use the AN adapter for what i hope will be a
pretty basic swap Thanks Chris
