"MSD High Pressure Electric Fuel Pump


This is head and shoulders better than any other pump I have
found so far. Not only is it only $109 but it is made in
the U.S. It is also a true positive displacement pump meaning
that it will draw fuel from a considerable head. That also means
it is a very linear pump with out put directly proportional
to pulse width or voltage.

It is very very efficient. at 40 psi with a pulse width of
50% (six volts) it will put out 20 gallons an hour which is about
what we need for take off and climb. Current drain should be around
2.7 amps. At cruise or 10 gallons and hour and a 25% pulse width
it should draw half of that or 1.35 amps. That gives you a long
time to find an airport on battery power alone if your alternator
dies.

If your planning a PWM constant dribble fuel system snap one of
these up before they raise the price :) Heck it would be great
for Tracy's system as well.

I am not going to mess with the Walbro/Mazda/Focus peripheral type
pumps. These are much much better for our purposes. No air sucking
problems.

Paul,

This MSD fuel pump appears to be the one I've been using since day 1.  It is
more than adequate for a turbo 20B at all altitudes tested--up to 17,000
feet.

I hope to have the Lancair flying again before Oshkosh.

Great news Tom. Hope to see you at OSH.
Maybe I'll come over and go for a ride if you don't mind.
