Have any of you ewp folks looked at CSR Performance products stuff?  They
tell me they have a high volume pump that fits into some good looking
anodized aluminum housings for big block car stuff that will pump  up to 70
gpm and is expected to last for 5500 hours or so; and, they have a  remote
that is something like davies-craig that is also expected to last  about 5500
hours and pumps around 35 to 37 gpm. They run in the $250 to $300  range,
supposedly use about 5 or 6 amps; and, I would like to learn from  someone
else's experimentation, if possible. <g>

Looks like somebody is dreaming in Technicolor. I sell DC pumps on my  web site. The smallest 3 GPM pump is using 5-7A and the pump is 3  pounds. Pump that will pump 15 GPM at 12V DC is about 30 pounds and  huge motor. There is no free lunch. Pumping 35-37 GPM on 5-7 amps? My  transponder needs 7 amps.
